What is the approximate time lag (in hours) from Gujarat to Arunachal Pradesh?
- A.1
- B.1.5
- C.2
- D.2.5
Correct answer
Explanation
The correct answer is C, two hours. The mainland of India extends from about 68 degrees 7 minutes east to about 97 degrees 25 minutes east, a longitudinal spread of roughly 29 degrees. Since the earth turns through one degree of longitude in four minutes, 29 degrees amount to about 116 minutes, that is nearly two hours, so the sun rises in Arunachal Pradesh about two hours before it rises over the Kutch region of Gujarat. Option A, one hour, is wrong because it would mean a spread of only fifteen degrees of longitude. Option B, one and a half hours, is wrong for the same reason, as it answers to about twenty-two degrees. Option D, two and a half hours, is wrong because it would need a spread of about thirty-seven degrees, more than the country has. This is why a single clock, Indian Standard Time, is kept on the meridian of 82 degrees 30 minutes east.
