Question 14

If the GMT at 0° longitude is 12 noon, find the local time of place A (30°E).

Answer

The difference in longitude between 0° and place A is 30° towards east.

Since, for every 1° difference in longitude the difference of time is 4 minutes.

Therefore, the local time of place A will be 30 x 4 = 120 minutes = 2hrs.

As, A is located to the east, it will be 2 hours ahead of Greenwich time: 12 + 2 = 14hr or 2 pm.

Therefore time at place A will be 2 pm.
