Q10. 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?
Ans:
• The longitudinal extent of India is 30^o.
• The sun rises in the east and sets in the west.
• It takes 4 minutes for the sun to move across 1 longitude. Thus, the eastern most point of India would be 2 hours ahead of the western most point (30 x 4 = 120 minutes), in accordance with the local time.
• This difference in time might create confusion in air and rail timings and so many other things across the two states. To avoid this confusion a longitude passing through the midpoint of 68^o 7' East (western most longitude) and 97^o 25' East (eastern most longitude) is taken as the standard prime meridian of India (i.e. 82^o30').
• The time at the standard meridian 82^o30' which passes through Mirzapur in UP is taken as the standard time of India, followed all over the country and hence the watches show the same time in both the states (i.e. Arunachal Pradesh and Gujarat).

(e) Ocean sea routes, i.e., Suez Canal route, Cape of Good Hope route, pass through the Indian Ocean.
