II.Improve Your Learning:
1.The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west. But the clocks show the same time. How does this happen?
A
1.The longitudinal distance is 30° between the Arunachal Pradesh on the east and Gujarat in the West.
2.One time zone is constitute 15° longitude in all distance.
3.As per longitudinal distance in India there are two time zones.
4.The sun rises in Arunachal Pradesh 2 hours earlier than that of Gujarat.
5.If in Arunachal Pradesh the time is 6:00 a.m. then in the Gujarat it is 4 a.m.
