At noon, ship A is 150 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 25 km/h. How fast is the distance between the ships changing at 4:00 PM?

My God. Short, simple and to the point. You're better than Khan academy in my opinion.

to DIfferentiate or NOT To differentiate.. THAT is the Question...

[@charlottevosaicake6480]

thats a sure thing ... it is really quick n easyy

[@UrbanFires]

Thank you. You made this problem a lot easier than it looked. :)

[@guggystyle]

Thanks for saying so!

This is an incredibly good explanation of what I just went to in class.

[@decreer4567]

Very clear explanation. The very beginning was super helpful with the hint that I was missing the d=rt. Moment I heard that I solved it then. Thank you.

[@EntertainmentUnit]

Thanks for this, something that worked for me was to model the situation as c^2 = (150 - a)^2 + b^2. This way, you don't have to worry about negating the 35 [km/h]. I'm not sure if this is more or less complicated though :-)

[@andrewzillges6911]

Thanks! You were very helpful!

[@asraffire5502]

Thank you sir! Great explanation! I understood really well!

[@rafeekasfragrancekitchen4789]

At 10am a ship A is at a distance of 40 km to the east from a ship B. Ship A moves at 12km per hour towards west and ship B moves at 16 kmph towards South.when will be the distance between them be minimum and what will be the value of this minimum distance?
Request to provide detailed solution

Solved this 2x with the wrong diagram... Hate these word problems.

A boat travels 40degrees north of east for a distance of 400km. How far North and how far East of its starting point does the boat sail

[@UserUnknown8570]

i don't even know

[@emanuelalemshet7486]

That was good one ☝️

[@whoppers7778]

ughh I did everything right except I forgot to make dx/dt negative. Ugh... .. ugh..

[@HoaMy-wh9pq]

I still don't understand why the da/dt equals negative 35. Can you explain it clearly for me?

[@chillgamer3171]

becuase it's technically a negative number, as it's moving east its going negative

[@willdinan9819]

@@chillgamer3171 im confused by this too. Wouldn't it be positive as it is going east and negative as it is going west since it is going to the left?

[@MushroomMan7]

i cant believe my professor used this question without even changing the numbers...

[@novab6710]

how did you get the 10 sqrt(101)?

[@guggystyle]

c^2 = 10^2 + 100^2 = 100 + 10000 = 10100. Now take the square root of both sides so that c = sqrt (10100). Break the sqrt (10100) into sqrt (100) * sqrt (101), which simplifies to 10sqrt(101). Does that help?

[@novab6710]

thank you so much WNY Tutor

[@guggystyle]

No problem.
