Detailed Solution

The above statement is true.
The longitudinal difference between Arunachal Pradesh and Gujarat is 30°.
One degree apart, the two longitudes differ by four minutes. Thirty degrees separate Gujarat from Arunachal Pradesh in terms of longitude. As a result, there is a two-hour delay between Gujarat and Arunachal Pradesh. One rotation of the Earth, or three-sixty degrees of longitude, takes twenty-four hours. Thus, it covers fifteen degrees of longitude in an hour and one degree of longitude in four minutes. This indicates that any two longitudes separated by one degree have a local time difference of four minutes. India spans thirty degrees of longitude. Hence there is a two-hour time lag between the easternmost and westernmost states' local times.
