Question

If it is noon at the greenwich meridian what will be the time at 10 degree west meridian?explain with calculation

Answer 1

Answer:

There are 360 degrees of longitude, 180 east and 180 west, and there are 24 hours in a day. So 360/24= 15 degrees of longitude for every hour change. 95/15= 6 and 1/3 so at 95 degrees W longitude it would be 5:40 AM. 100/15= 6 and 2/3 so at 100 degrees E longitude it would be 6:40 PM. 20/15= 1 and 1/3 so at 20 degrees W longitude it would be 10:40 AM. 120/15= 8 so at 120 degrees E longitude it would be 8 PM.
