Question

For every degree of longitude the time difference is four minute .explain .

Answer 1

As we all know, the sun rises at different times in each place. The four minute lag is because the sun rises four minutes late in each longitude. For example, in India, there is a time lag of two hours from Arunachal Pradesh to Gujarat.

Answer 2

Answer:

Time taken to rotate 1 time: 1 day

1 day: 24 hours or 1440 minutes.

Degrees turned in one rotation: 360 degrees

Time taken to turn 1 degree longitude: 1440/360 = 4 minutes

Thus, to complete one degree of longitude, it takes 4 minutes
