Question

The time of places at same longitude is always the same and from east to west on different longitudes it is different. Explain.

Answer 1

The time of places at same longitude is always the same, so when we proceed towards 1° east to know the time of a place, 4 minutes are added to the local time of that place. In the same way, when we move towards 1° west, we subtract 4 minutes from the local time of that place.
