Question

Answer 1

heyaa..
there is a difference of 4 mins between each degree of longitude...

Gujarat lies between 68° E and 74° E longitude and whereas, Arunachal Pradesh is located between 91.20° E and 97.30° E longitude. So, approximately both the states have 29 degree longitude difference in term of location.

{29 × 4 = 116 (approximately 2 hours}. Therefore, Arunachal Pradesh is 2 hours ahead of Gujarat in term of local time.
