so to sum up the video:
calculate: time to longitude conversion
________________________________________
step 1) identify in question where west longitude, meridian and east longitude are compared to each other.
step 2) find the time difference = if west time is given substract the west time with the east time ( ensure all are in the standerd 24hr time not 12hr one) / if east time is given add the east time with west time.
step 3) conversion from hour to min = turn the found number in hr and min to only min.
step 4) as 4 min= 1 longitude, calculate the value of found min into longitude (ans)
calculate: longitude to time conversion
________________________________________
step 1) step one of the previous method.
step 2) find the time difference = if west longitude is given add the west and east longitude/ if east longitude is given substract.
step 3) multiply previously found value with 4
step 4) convert min into hour
step 5) if, the question demands the local time of the specified place then add( if the asked place is east) and substract ( if the asked place is west) the found time in step 4.
thankyou for the video, it ensured me 10 marks in my gs exam and this is a little short summery for people with further confusion. beware: I am also a class 10 examiner so i dont know more than i've been taught if i made any mistakes, inform me. good day.
thank u for this! saved so much time
Bro wasted the whole video, why didn't I get this comment before 😅
Sir i was crying how to do then I found your video it was just amazing I did it so nicely and thank you so much sir to spread your support for us
To find the local time in West Africa (at 20°W longitude) when a program was broadcast from Mumbai at 7:30 p.m., we need to calculate the time difference between Mumbai and West Africa.
1. Mumbai (72.8°E) to Prime Meridian (0°): Mumbai is ahead of the Prime Meridian, so we need to subtract the corresponding time difference. Since every 15 degrees of longitude corresponds to a time difference of 1 hour, Mumbai is approximately 4 hours and 51 minutes ahead of the Prime Meridian.
2. Prime Meridian (0°) to West Africa (20°W): West Africa is behind the Prime Meridian, so we need to add the corresponding time difference. Since every 15 degrees of longitude corresponds to a time difference of 1 hour, West Africa is 20°W, which is approximately 1 hour and 20 minutes behind the Prime Meridian.
Now, we add the time difference between Mumbai and the Prime Meridian to the time difference between the Prime Meridian and West Africa:
4 hours and 51 minutes (Mumbai ahead of Prime Meridian) + 1 hour and 20 minutes (West Africa behind Prime Meridian) = 6 hours and 11 minutes.
So, the local time in West Africa when the program was broadcast from Mumbai at 7:30 p.m. would be approximately 1:19 p.m. on the same day.
Sir can you tell ans of this ques
After 20 mins I have my exam and your video saved me, now going to school after knowing the time calculation. Thanks sir
Same here 😅

Thank you Sir for explaining this topic.

Tysm...sir m so thankful of having a teacher like you here out...god bless you sir...tomorrow is my exam nd M watching it now as a beginner nd now M doing PHD in Calculating time 😂
What a great video Sir ! The teacher like you made education easy ....
12:49
Sir, the in the first question,
The time difference is 138.75 degree and not the longitude of the place.
So, after subtracting,
138.75 - 88(From Chicago's longitude to Prime Meridian) = 50.75 degree.
Therefore, the longitude of the place shall be: 50.75 degree East.
i.e. 50°45' (Thanks @VampyboiFTW )
Is the answer right sir?
And sir, online solutions say the answer is 50° 45′ E... And I got 50° 75′ E... So where have I gone wrong?
@@ThejasRP its not 50°75' its 50.75° = 50°45' (since we have only 60 minutes we have to take 75% of 60 = 45)
@@vampyboiftw Oh, Thanks!
@@vampyboiftw hey what if I write only 50.75 is it wrong or right
Yess!!!
