Question

If the GMT at 0° longitude is 12 noon find the local time at place A (90°E)​

Answer 1

Example: If it is 12 noon at Greenwich, calculate the local time of the places located on the 69o E. 105o E = 105 x 4 = 420 minutes i.e., 420 ÷ 60 = 7 hours Time on Greenwich is 12:00. So, time on 105o E is 12 + 7 hours = 19 or 7 p.m.
