Question

If it is 12noon at 60 degree east longitude ,then explain what would be the time at 30 degree west longitude?

Answer 1

Answer:

6 am

Explanation:

For every 1° change in the longitude, the time changes by 4 minutes. Therefore for 60-(-30)= 60+30= 90° difference in longitude, the time difference is 90×4= 360 mins. Since any place which is on the west of another place lies back in time, we subtract 360 mins(6 hours) from 12 noon which comes to be 6 am.
