Professor Fukanō, the famous scientist, has embarked on a new challenge - piloting around the world in a plane of his own design. There’s just one problem: there's not enough fuel to complete the journey. Luckily, there are two other planes to help. Can you help the professor fly for the whole trip and achieve his dream, without anyone running out of fuel and crashing? Judd A. Schorr shows how.
Lesson by Judd A. Schorr, animation by Artrake Studio.
“The professor probably could have designed the plane to hold more fuel, but where’s the fun in that?”
Me: NOT DYING
lmfao this made me chuckle
THIS MADE ME DIE ON THE FLOORRRRRRRRRR💀
And where's the fun in that?
Your dying
@@SacsachCCABP so?
For anyone wondering, Fukanō (Fukanou) means "impossible" in Japanese.
What I was saying
No one was wondering
I was about to comment that 😂😂😂
😮
Do the other two mean anything? Google Translate says Fugori is falsehood and Orokana just comes back as Orokana. I know it works pretty well, but I’d trust someone with personal knowledge over the program.
he doesn’t even need to fly around the earth nonstop, being able to make a plane that goes over 5 times the speed of sound is impressive enough
this comment is severely underrated
Fukano. *builds a revolutionary supersonic airplane*
Also Fukano: M O R E !
And being able to dock a fuel nozzle midflight at that speed instantaneously too!
actually, the real world X-15 goes at mach 5.93 making it almost 1 speed of sound faster
@@crow2464how much fuel does that consume?
Me: Hears first part of puzzle.
Me: This is easy
Narrator: Fugori and Orokana cannot crash
Me: damn, there goes my strategy
What was your strategy?
Just curious
@@sabereagle9277 Originally, it was very easy... you just have Fugori follow the first plane and give all of its fuel once it has the same amount remaining as the first plane has empty capacity. Of course this means Fugori crashes and dies. Orokana does similar but the opposite way around the world and with a pause to wait for the right time.
This doesn't work when Fugori and Orokana have to survive :) Though, the answer is somewhat similar.
@@ericfleet9602 oh okay
"some of you are probably going to die, but that's a sacrifice i'm willing to make" lol
@@Iggybart05 idk man, i still think that Fugori and Orokana are disposable...

BG - 11KM - Port Credit SS (2272) he was building his own rockets? As in rocket ships? Was he alone building these first of all?
I just realized. In order for the professor to travel around the globe at 1 degree longitude per minute, he'd be travelling roughly 4,150 miles per hour!
Well at exactly 3600 nm/h
probably faster, as that is assuming he is literally dragging his plane on the water the whole time. any elevation above sea level increases the circumference of his journey, thus he must increase his speed to maintain the 1 degree per minute.

There are 2 optimizations that can be made to the solution.
1. Fugori can actually travel past 90 degrees with the professor, if Orokana, after refueling, heads back out to help Fugori on the way back to base.
2. Orokana can meet the professor with more fuel at 270 degrees if Fugori accompanies her when moving clockwise, and refills her tank to full after 60 degrees.
With this optimization, a fuel tank with capacity 162 kiloliters is sufficient - the professor can be left with a full fuel tank 99 degrees out, and meet up with an assistant as he runs out of fuel, 99 degrees before the end of his trip.
Why hasn't Ted Ed pinned this comment lmao
But Orokana and Fugori would take time to reach back to the airport and then take even more time to fly east to meet the prof. By that time prof would be dead
@@thesmartnerd732 Well, technically the prof could go on another 9 degrees to the 279 degree point, wich is exactly what they need to meet up with him since on of the planes left at 99 degrees and 180 degrees to the other direction is 279, the problem with that is that it doesn't offer a solution in wich "meet the professor with more " as the comment said would be possible
@@josephc.9520 Because he's wrong. As TheSmartNerd says, if Orokana helps Fugori return to base, they can't get to the professor in time. Stern Huang doesn't justify his figures of 162kl tank size and 99°-261° for the professor's solo flight, but we don't need to look at those specific numbers to see the problem.
Let's assume just a 1°/kl optimization. Professor Fukano begins flying solo at 91° with 179kl fuel. As in the original solution, he will reach 270° and run out of fuel at the 270 minute mark. That's 90 degrees from base; therefore, to meet him at that time, someone must take off 90 minutes prior, at minute 180.
But wait! Fugori was with the professor at 91°. A round trip takes 91 minutes for each leg, so Fugori cannot reach base until 182 minutes have elapsed. If Orokana helps Fugori, neither of them can be at the base to take off at minute 180, so the professor will crash. If she's en route to the professor at minute 180, she cannot have met and refueled Fugori, so he will crash.
The solution is already optimized.

But plot twist, Fugori and Orokana were always jealous of the professor, having stolen their design for the plane and giving no credit where credit was due. So when the time to give the Professor his fuel came, the two left with no transfer of fuel. The Professor plummeted to the ground thinking the tubes had malfunctioned, and died.
Fugori and Orokana flew back to the airport and found a small party had been thrown together (planned by the professor) with streamers and balloons in honour of the two assistant's help with the project, as well as an offer at a full time job alongside the professor. As the fellow scientists and plane technicians on the ground saw Fugori and Orokana leave their planes, the only question on their minds was "Where is the professor?". The two lied and said that they had not see him where they agreed to meet.
Overwhelmed with guilt, Fugori and Orokana took off once more after refueling, claiming they would go back to look for the professor at the spot where he had fallen. They were never heard from again.
Nicolas K (slow clap) well done
Swigity Swooty I'm coming for that booty
No, they were heard from again. They landed back in Tokyo and were met with heavy fines after losing a case after Fukano's family sued them for deliberating getting rid of a loved one's life and so the assistants were fined heavily.
They were charged with illegally landing aircraft and neglecting a comrade's life. They were very controversial.
Jacob Griffin But nobody ever saw them again. Did they die? Did they go into hiding? Did they start anew as farmers, cut off from society, to repent for their sins?
Nicolas K
Did they fly into the Bermuda Triangle?
I figured it out but in a differnt way. Let me explain, also I will use the amount of fuel they have in % instead of using the exact amount like shown in the video to make it easier.
We know that all of your fuel will take you to just the other side of the planet and you can only land on one spot which is the airport you started from.
To accomplish this task ive decided to devide the whole trip around the globe into 10 sections. Every section is exactly 36 degree of longitude (One tenth of the whole trip).
Due to our understanding that half the trip will take up 100% of our fuel we can safely assume that every section will take up 20% of our fuel.
So basically. 36 deegres of longitude = 1 section = 20% fuel.
Now to the actual flight we will (just like in the video) fly every plane west. But instead of stopping at 1/8 (or 1.25 sections) of the total flight you will now stop at 1/5 or exactly 2 section. All the planes should now have 60% of their fuel left and has all used 40% of their fuel to get there. Plane 2 and 3 will now transfer 20% of their fuel to plane 1 (each) which will put plane 1 at 100% fuel while the other planes will have 40% each. The second and third plane will now have exactly enough to fly back to the airport to refuel for their next mission. Meanwhile plane 1 will have just enough fuel after the refuel to go 180 degrees of longitude plus the 72 it has already travelled which puts the total at 252 degrees of longitude or in more simple terms, 7 sections.
Meanwhile, plane 2 and 3 has refueled at the airport and plane 2 has gone 3 sections or 108 defrees longitude and has now reached plane 1. With the remaing 40% they split it even and can now go one more section. Meanwhile plane nr 3 has also gone east and meets up with plane 1 and 2 and they all split the fuel to get 20% each. With this fuel they all aim for the airport and they all crash in the pacific, 18 degrees of longitude from their destination and Fukanōs dreams were crushed and yes I just made you read all that and yes I thought it would work while writing it.
he can glide if hes high enough :D
So god darn close
Not only his dreams getting crushed there
Wow I read that whole thing that was hilarious!!! Also I’m pissed.
Lmao , I have a better solution . Why can't the planes stack on top of each other ?Assistant #1 will carry both Assistant #2 and the professor . At the 180 degree mark , they'll switch places and then Assistant #2 will carry Assistant #1 and the professor to the airport to complete the trip and the professor still has his fuel tank completely full.
Don't worry , I'm only kidding.
I came up with another solution to the riddle.
12:00 → all three planes depart
12:00 - 12:45 → assistant C and B and the Professor fly 45 longitudes from 0°l to 45°l
12:45 → assistant C transfers 2x 45kl, the other two pilots now have a full tank again
12:45 - 13:30 → assistant B and the Professor fly 45 longitudes from 45°l to 90°l
13:30 → assistant B transfers 45kl to the Professors plane, the Professor has now a full tank again
13:30 → assistant B has 90kl fuel left, which is enough to fly the 90 longitudes back home
13:30 → assistant C arrives back home
13:30 - 16:30 → the Professor flies 180 longitudes from 90°l to 270°l
15:00 → assistant B arrives back home
15:00 - 16:00→ assistant C and B fly 60 longitudes from 360°l to 300°l
16:00→ assistant C transfers 60kl to assistant B, assistant B has now a full tank again
16:00→ assistant C has 60kl fuel left, which is enough to fly the 60 longitudes back home
16:00 - 16:30→ assistant B flies 30 longitudes from 300°l to 270°l
16:30 → assistant B transfers half of his tank to the Professor. Both have 75kl fuel
16:30 - 17:45 → assistant B and the professor fly 75 longitudes from 270°l to 345°l
17:00 → assistant C arrives back home
17:30 - 17:45 → assistant C flies 15 longitudes from 360°l to 345°l
17:45 → assistant C transfers a third to assistant B and the Professor, everyone has 55kl fuel
17:45 - 18:00 → assistant C and B and the Professor fly 15 longitudes from 345°l to 360°l
18:00 → all three planes arrive safely back home with 40kl fuel in each tank.

I like how they helped us in a sneaky way on that 30 second mark, when they actually displayed what fuel meter looks like, so if you are paying attention you realize that you will be transferring 45 kiloliters around.
Ted-Ed: "Can you solv-
Me: "Oh, Fukano!"
A few seconds into the explanation, my first thought was "Oh, they're allowed to land and take off again?"
Kinda gets easy then, so I didn't consider the possibility.
fukano means impossible in japanese
fugori means nonsense and orokana means stupid
oldcowbb oh shit
i thought it meant fuck no in english
stupid impossible nonsense
“The professor could’ve designed the plane to hold more fuel, but where’s the fun in that?”
Goddamn it, I give up-
I have a different solution: All three Planes start simultaniously, heading west. After 30 Minutes, Assistent 2 gives each other 30 kl and heads home again. At 60 Minutes, A2 reaches home, refuels (has to be as fast as transferring fuel between planes, else this doesn't work) and heads off west again. At 90 Minutes, A1 transfers 60 kl to the professor and heads home. At 120 Minutes, A1 and A2 meat, A2 transfers 30 kl to A2, they both head home. At 180 Minutes, they reach home and refuel, heading east afterwards. At 210 Minutes, A2 transfers 30 kl to A1 and heads home. At 240, A2 reaches home, refuels and heads east. At 270, A1 reaches the Professor and transfers 60 kl. At 300, all meet, A2 transfers 30 kl each to everyone, so everyone has 60 kl left to head home
I had to think long and hard about it. I did not think it was going to work because of how it looked to me like you were transferring fuel too early in the beginning but it did. Nice job.
See mine - (calling the 2 side planes A and B)
1) first part same as explained in video
2) as soon as B returns to airport, A and B takeoff
3) After 60 mins A gives 60 kl fuel to B and returns
4) Professor and B meet 90 degrees from airport, B gives half the fuel (75 kl) to prof.
5) After 75 mins, A is back with (180-15) kl of fuel, give B 15 kl and keeps 15 giving prof. 135 kl
Since fuel is left it means they can do the job with max capacity less than 180 kl
Johanniklas Lp BRUH
Also found a different and much less elegant (more complicated) solution:
All planes leave west. After 72 minutes both assistants transfer 36 kl to the professor (have not seen any rule that says they cannot transfer fuel simultaneously), and head back home. At 144 minutes they reach home, refuel and take off instantly, flying east. At 216 minutes, assistant 1 transfer 72 kl to assistant 2 and returns home. Assitant 2 continues to meet the professor at 252 minutes, transferring half his tank (72 kl) to the professor. Assitant 1 gets back home at 288, refuels, and takes off instantly, reaching the other two at 324. It transfers 36 kl to each of them and they all return home. In the end, assistant 1 still has 72 kl left in the tank.
@@shotguneu I believe assistant 1 would crash. If assistant 1 and 2 leave headed east at 144 minutes and travel together until 216 minutes (72 miles traveled together) and then assistant 1 transfers 72 kL to assistant 2 (180-72-72=36) that would leave assistant 1 with 36 kL left while still being 72 kL from the airport.
nope.

Been coming here for a while now. Love your voice. You're amazing. Keep up the good work!
I'm sure others have discussed this but I just found this video. I came up with a different solution but when I did the math, it turns out the solution in the video uses less fuel.
My solution was to have P3 refuel P1 and P2 at 45 and fly back. P2 refuels P1 at 105, and flies back. P2 will hit 0kl at the 45 degree mark. P3 leaves at 120 to go to the 45 mark and refuels P2. They fly back to the base together. P2 refuels back up to 180kl, but P3 only needs 135kl to refuel. They do this instantly and fly in the opposite direction.
At 255, P3 refuels P2. P3 flies back and lands at the base with 45kl left in his tank. P2 flies on to 285 where he meets the professor. P2 refuels P1 so they both have 75kl left. They fly back to the base and land with 0kl left in their tanks.
My solution uses 1035kl for fuel and ends with 45kl left in the tank for a net of 990kl used. Their solution uses only 900kl of fuel.
Simple, professor Funkand uses his shrink ray to make the earth 50% smaller, then all three planes fly around.
lol
Lol
It will have 360 degrees at any size
then say goodbye to the following
> the three pilots
> their planes
> gravity
> all 7.6 billion people
but there will be less distance from the airport and to the airport :D
"But lets get real" then says they can turn on a dime and instant refuel each other
I did it differently. I didn't try to minimize the amount of fuel used since that wasn't part of the riddle. My method uses 1020kL whereas theirs use 900:
60 min:
Plane A. 120+60=180 kL
Plane B. 120-60=60 kL
Plane C. 120 kL
Plane B flies back.
80 min:
Plane A. 160+20=180 kL
Plane C. 100-20=80 kL
Plane C flies back.
120 min:
Plane B lands and refills.
160 min:
Plane C lands and refills.
Both take off in the opposite direction.
220 min:
Plane B. 120+60=180 kL
Plane C. 120-60=60 kL
Plane C flies back.
260 min:
Plane A. 0+70=70 kL
Plane B. 140-70=70 kL
280 min:
Plane C lands and refills.
300 min:
Plane C takes off.
330 min:
Plane A. 0+30=30 kL
Plane B. 0+30=30 kL
Plane C. 150-60=90kL
360 min:
Plane A. 0kL
Plane B. 0kL
Plane C. 60kL

This is really good but I hate how nobody understands that planes can glide around for hours without fuel
Mika Stojkovich that's not the point. The planes are just a way of relating the riddle to the real world. It's the math that matters

Here is how I would solve it.
Step 1: Tell the fuel tank that I have green eyes.
It’s not possible because when you switch directions you would probably snap your neck due to the sudden change in direction combined with the g forces.
For all of you who say "Make a larger tank" Know that that's not the point, the planes where just physical representations of the problem

There's another solution:
EDIT: Everything below is incorrect
1. They leave West at noon
2. At 1:00 Fugori gives 60 kl of fuel to professor Fukano
3. At 1:20 Okokama gives 20 kl of fuel to professor Fukano
4. At 2:00 Fugori returns and refuels
5. At 2:40 Okokama returns and refuels
6. At 2:40 Fugori leaves East
7. At 4:00 Okokama leaves East
8. At 4:20 (lol) Fugori gives 40 kl of fuel to professor Fukano
9. At 5:00 Okokama gives 60 kl of fuel to both Fugori and professor Fukano
10. At 6:00 they all return to the airport
Sorry mate, but you are wrong. If Fugori leaves at 2:40 to reach the professor at 4:20 (when the professor will be out of fuel according to your refuels), he will have traveled 1 hour(60 minutes) and 40 minutes, meaning a total of 100 minutes, which means 100 kl. So even if he didn't give any fuel to the professor(which he must for your plan to work), he wouldn't be able to return because he would need another 100 kl.
@@Georgetsiki13 Yea, my mistake was that I knew Okokama could save either one of then, but I accidentally thought "both" instead of "either" (but idk for sure cus I made this awhile ago).
Step 1: Check if you have green eyes.
Step2: Ask the airplane to keep going
A riddle, or a math calculation?
math calculation, it's tough
Is it? It seemed to be basic adding and subtracting.
Zox Sonic It's not a riddle. Just math.
Hans Smirnov Thats Maths isnt it?
Zox Sonic it's physics.
nah, both assistants are super dead. no way they survive the massive g-forces involved in "turning on a dime" at those speeds
Nah, you super pretentious with your "facts" go cite your sources.

Plot twist: The professor spent so much time designing he forgot to train. Good luck crashing
Never ever change your narrator
fukanou = impossible
fugouri = irrational
orokana = fool
he shouldve chosen a team with different names
Didn't notice that before your comment, LOL. I guess Ted-Ed didn't expect some of the CZcamsrs here could understand Japanese.
Water Spray I believe it's intentional. kinda like a hidden joke
Professor Fukano makes sense
It's impossible, irrational fool!
TheNinjas lmaoo
I found a different solution that works assuming that refueling is instantaneous. Instead of just one plane (Orokana) going in the opposite direction to meet the Fukano at the 3/4 mark and then both being refueled by the third plane (Fugri) on the way back, you can have two planes setting out together in the other direction and one giving fuel to the other on the way with enough fuel to make it back. At the 3/4 mark when the two remaining planes meet, they both just have enough fuel to make it back. It's really the same solution but different order.
By the way, I love the Japanese names 不可能 (impossible), 不合理 (unreasonable), and 愚かな (foolish)
Your method cannot be done. To get home from 3/4 point, two planes both need half a tank. Meaning you need one full tank and disperse it between the two. You cannot get 1 plane to 3/4 with a full tank.

Simgen x This alternative solution works if the plane that got home takes off a third time to give 45L to the plane that needs it on the final way home. Therefor this solution is less optimal than the one in the video
Simgen x
Sorry, it's a little hard to explain without diagrams. While Fukano was going the long way around, I had the two other planes going in the opposite direction with one giving excess fuel to the other and then returning. When they meet at the 3/4 mark they have enough fuel to get back because there is further support from the other plane that did not go all the way to the 3/4 mark. This solution has more steps that the one in the video. It also assumes that refueling on the ground is instantaneous which was not really specified in the rules (although implied). The video solution is much better.
+blabby102 Your solution is incorrect. Assuming two planes go the other way, at the 3/4 mark, both would have to start to come back for them to survive. They would not have any excess to supply to each other for one to meet Fukano and survive. If you really want another answer to this, Fukano could literally just bring the two tanks in the other planes with him and refuel midair. He doesn't want to redesign, but he can just let the tanks dangle along some rope or sit with him.

Imagine going that fast and just turning around instantly, goodbye spine
1:29 He is already doing it!!
Yes... This one is fairly easy
Quinn Gauder yes I am very smart I can figure out riddles in 3 seconds. :b
Yesman
yep.
There are solutions that don't require two planes to be refueled at once.
A, B and C fly to 60 degree mark. C transfers 60 units of fuel to A and turns back.
A and B fly to 90 degree mark. B transfers 30 units to A.
B flies back to 30 degree mark where C meets him to refuel him. Both return to airport, refuel and take off again in the opposite direction.
At 330 degrees, C transfers 30 units to B and returns to the airport.
B flies on to 270 degrees to meet A. B transfers -half of his- 90 units to A, keeping 30 for himself.
A flies the remaining 90 degrees to the airport.
C has meanwhile refueled and meets B at 300 degrees, transfers 60 of his 120 units and they fly to the airport.
DrGerbils plane c wouldn't be able to make it back to plane b in time to refuel it
Fukano: “What did Fugori leave me to listen to?”
James Hetfield: “GIMME FUEL, GIMME FIRE, GIMME THAT WHICH I DESIRE!”
If you devide the globe into 8 parts as in the video you can also use another strategy in Fukanos last 3 hours.
With Plane 2 and 3 loaded up with 180KL fuel each they both fly east for 45 minutes ending up with 135KL each, but 45KL from Plane 3 is transfered to Plane 2.
Plane 3 goes back to the airport to refuel meanwhile Plane 2 and Fukano meet at 270Longitude. Fukano has 0KL Fuel, meanwhile Plane 2 has 135KL. Plane 2 transfer 90KL to Fukano which is enough for Fukano to go back home.
Plane 2 on the other hand doesn't have enough and will run out of fuel at 315 Longitude with 45 minutes left but Plane 3 is there to meet up and Transfer 45KL extra to Plane 2 and both planes makes it back with Plane 3 having 90KL to spare.
the professor made a plane for fun and if he fails to get fuel thats his fault
well i got all 3 of them crashing together 20 degrees short of the goal.
*scene: planes running out of fuel with all the turbulence, panic lights, and beeping sounds*
"it will be an honor to die with two of my most dedicated students."
"you were the best professor i ever had, dr. fukano."
"i.. i've always loved you, orokana!"
"i feel the same way! oh fugori, if only you hadn't waited 'til now, our love could have blossomed into beautiful math!"
"then our love shall burn in our hearts as brightly as our planes hurdle into the earth!"
"but wait, jet fuEL CAN'T MELT STEEL BEA--***C R A S H***"
such a tragedy ;__;

There is an another way
we're all dying so the professor must go
So the rotation of the Earth never comes into play? I may have been over thinking this.
Leon Hager bruh the earth is flat dummy
Planes fly in the atmosphere, which is held into place with Earth's orbit by its gravity, I think. Anyway, it does not come into account.
But the earth itself is rotating below the planes.
Factoring the earth's rotation doesn't change much. It only increases the starting velocity of the planes.
For example, if the earth "spins" at 100 mph at the equator, then while standing on the equator I also have a velocity of 100mph. Side note this example is VERY simplified
But can the air's density change it? www.braeunig.us/space/atmos.htm . There is a wide different between air's density on the ground and at the height of 20km.
I got the answer but would like to add that the parameters allow for slight variations and extra fuel in various spots.
The important part in the parameters is this: Refueling doesn't have a time cost.
This means that Orokana could have only given fuel to the professor, returned back to refuel and then met Fugori at the 45 mark to refuel him. They both get back with a bit of fuel to spare.
Then they can both leave instantly (refueled of course), one of them refueling the other at the 45 mark again, returning again to refuel and then going back with more fuel. The other continues to the 90 mark to meet the professor as normal - now having fuel to spare for the return trip. Although that spare fuel isn't enough for the full way back with both planes, the first plane going back to the 45 mark will compensate.
What I'm wondering (and is a much harder question than the riddle) is whether this strategy would allow for a smaller tank of fuel. Maybe the support planes could get the professor to the 95 mark and meet him at the same on the other side? Then a tank of 170 kL would be enough. The main difficulty here is the timing. Both support planes can't get to the airport together, or they won't have time to meet the professor.
My educated guess (I made a few preliminary attempts) is that it's impossible... but I'm not entirely sure.
If even one of them didn't time their take off and return perfectly, they would probably al die.
This is the only Ted Ed riddle I’ve been able to solve lol
Vertical distance was not accounted for. The planes crashed.
Neither was any sort of turbulence whatsoever, but that's just over-complicating things. Also, you'd have to refuel in 0 seconds or the plane will crash during almost every refuel.
Yeah.
Go to 1:39 and read #3: The planes can transfer the fuel instantly, i.e. 0 seconds.
Andy Schlachter s
earth rotation not accounted for after the 6 hour flight the airport would be another 90deg ahead which would take 90 min to get to but in 90 min the earth would have rotated another 22.5d which would take 22.5 min to travel and so on

Case in point
we have all something to learn ^~^
yes you are really the smart one, I now I saw my mistake =) haha
Why can't you just fly against the rotation of the earth?
Because you still have a rotational velocity with the earth, meaning the world will not spin around below your feet, so you have to travel the distance yourself. The only reason why flight west to east vs east to west takes diffrent times is because the winds travel in a certain direction
Because conservaion of momentum lol
The planes are still in the atmosphere. Since the atmosphere rotates with the earth, that's not possible.
Robert Hardeman
It is since earth's rotation causes winds to go a certain way around the equator. It's not the whole atmosphere but it's the air they'll be traveling into.
No.
Solving this riddle on an airplane randomly is magic!!!
Are you guys proud of me this is the first even ted riddle i was able to solve without looking uo yha answer
in my solution they all explode in mid air, and I'm a mathematician but can't find a way around it
Alex Raxach then your pretty stupid because this was one of the easy riddles
ImYourSenpai No need to call him stupid. Why are people so rude nowadays?
no kidding, and i imagine he was joking since there is no reason for anything to explode, only run out of fuel and crash if that what was meant..
Vatsyayana the reason for the planes to explode would be atmospheric friction, but I was kidding anyway.
I'm an engineer. Here's the more simple solution: bring the gas tanks of the other planes with the professor. 1.5 times the amount of gas, able to refuel in the air, nobody dies, continuous trip: it follows all the rules stated, even the professor's intention of not wanting to redesign. He simply brings more that's not designed into the plane which may add to the mass, but 1.5 times the amount needed is well over enough.
Honestly I'm so bad at even small numbers maths that it hurts my brain to even try, but I adore riddles so I watch them anyway without trying to solve these ones :')
I prefer logic, language, verbal reasoning, riddles with context clues, where are they at!
I got a really good one, the answer is also very logical (don't use dumb reasoning to answer this question). Please try it out, I think you'll really enjoy it and get a great sense of accomplishment if you get it.
In a far away land, it was known that if you drank poison, the only way to save yourself is to drink a stronger poison, which neutralizes the weaker poison. The king that ruled the land wanted to make sure that he possessed the strongest poison in the kingdom, in order to ensure his survival, in any situation. So the king called the kingdom's pharmacist and the kingdom's treasurer, he gave each a week to make the strongest poison. Then, each would drink the other one's poison, then his own, and the one that will survive, will be the one that had the stronger poison.
The pharmacist went straight to work, but the treasurer knew he had no chance, for the pharmacist was much more experienced in this field, so instead, he made up a plan to survive and make sure the pharmacist dies. On the last day the pharmacist suddenly realized that the treasurer would know he had no chance, so he must have a plan. After a little thought, the pharmacist realized what the treasurer's plan must be, and he concocted a counter plan, to make sure he survives and the treasurer dies. When the time came, the king summoned both of them. They drank the poisons as planned, and the treasurer died, the pharmacist survived, and the king didn't get what he wanted.
What exactly happened there?
CaptainRay The treasurer found a weak poison to drink before he was summoned, so that he would then drink a stronger one from the pharmacist...he took a regular potion not a poison so the pharmacist wouldn't drink anything stronger, but the pharmacist worked this out and did the same, so the treasurer wasn't neutralised, and the pharmacist never drank any poison at all. The king wanted the strongest poison but he got a useless potion so he didn't get what he wanted??
CaptainRay Nooo I mean the treasurer figured out the pharma's plan and also brought in a useless potion, not a poison
Maybe not 'potion'. Imagine if they brought Pepsi lmao.
CaptainRay Instead of bringing poison, treasurer brings Pepsi. He knows pharma will die because his 'poison' which is actually Pepsi, won't neutralise the pharma. Also, treasurer drinks weak poison before he is summoned so the pharma's poison will neutralise him, but the Pharma works out this plan and also brings Pepsi. The treasurer dies because he didn't get his poison neutralised, pharma stays alive because he never drank any poison, but king doesn't get what he wants because he's just left with useless Pepsi instead of the strongest poison
Imagine the anxious feeling waiting for the plane to arrive when the fuel is just almost finish and finally seeing the plane and transfer fuels at the three-quarter mark
There's another strategy for each assistant going in opposite directions when the professor is getting to the 25% and 75%
thought so too at first, but that would not work. At 25% they have burnt half their fuel. so the assistants can either return to base or refuel the professor, but not both.
Nope. At 25 percent assistant plane used half of his fuel and cant help professor at all. You got to do like in the video, for example
