Question

What is the time at a place A (125-degree W) when it is noon at Greenwich?

Answer 1

Answer:

Explanation:

04:00

Answer 2

Answer: 3:40

Explanation:

Difference of longitude of place A and Greenwich = (125-0) =125 degree

We know for 1 degree longitude there is a time difference of 4 minutes.

So, 1 degree longitude = 4min

125-degree longitude =(125X4) = 500 min or 8hrs 20 min

Now the place A is located at the west of Greenwich so 8hrs 20 min needs to be subtracted

from Greenwich time.

The time at place A is

12 hrs.- 8hrs. 20 min= 3hrs. 40 min or 3:40am
