3 The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat
in the west but the watches show the same time. How does this happen?
The central location of India at the head of the Indian Ocean is considered of
great significance. Why?
Answers
The time difference between any two lines of longitude 1 degree apart is 4 minutes. We know that because the earth rotates once in 24 hours. There are 360 degree of longitudes so the time difference between any two consecutive lines of longitude 1 degree apart will be 4 minutes.
The earth rotates once in 24 hours( 24 × 60.) There are 360 degree of longitude. So, the time difference between two consecutive lines of longitude is 24 ×60/360= 4 min.
The longitudinal difference between Arunachal Pradesh and Gujarati 360 so time difference is 30×4 = 120 minutes = 2hours.
