Correct option is B
The correct answer is indeed (b) 2 hours.
· India’s longitudinal span is from 68°7'E (Gujarat) to 97°25'E (Arunachal Pradesh), covering approximately 30 degrees. Since the Earth rotates 15 degrees per hour, the time difference can be calculated as:
Time lag=
Longitude difference=97.25°−68.07°=29.18°
Time lag=(approximately 2 hours
Thus, the time lag between Gujarat and Arunachal Pradesh is approximately 2 hours.
Additional Information:
· The easternmost region of India (Arunachal Pradesh) experiences sunrise about 2 hours earlier than the westernmost region (Gujarat).
· Despite this geographical time difference, India follows a single time zone (Indian Standard Time, IST) to maintain uniformity across the country.
