Question

What will be the time on longitude 45 east when the time is 9:00am on longitude 15 east?
​

Answer 1

■ Difference in longitude = 45–15=30

■ If we start from 0° longitude (Prime Meridian) to east, with one passing longitude 4minutes will added.

■ So, 30 X 4 = 120 minutes = 2 hours ahead

■ So, time on 45°East will be 9 + 2= 11 am.
