Answer 1

Answer:

the approximate no.of longitude in india are 30

to travel 1 longitude it takes 4 min.

(30*4=120)

therefore sun rises 2 hours faster in arunachal parades

but to avoid confusion we choose 82 degree 30 min. as our Indian standard time

Answer 2

#Answer :

The longitudinal gap between Arunachal Pradesh and Gujarat is about 30°. Due to this, there is time lag of about two hours between these states. Since Arunachal Pradesh is in the east hence the sun rises earlier here compared to in Gujarat. The Indian Standard Time is taken from the time of Standard Meridian of India and hence, the watches show the same time in both the states.
