Question

You are in india whoes prime meridian is 82 30' e logitude.If the time here is morning 11right now.What will be the time in a country whose longitude is 52 30'e longitude?

Answer 1

Since the longitudinal extent had been given of 52° 30'e and we are provided with 82° 30'e ie. the longitudinal extent of India, we have the following formula:-

Time difference between two longitudinal lines= 4 min

Now,

longitudinal difference= 82°30'e - 52°30'e

=30°

Therefore,

Time = 4 × 30

= 120 min

= 2 hrs before 11am (since, longitude is decreasing and we are moving towards Greenwich)

Required time = 11 - 2

= 9 am
