Give reasons :

There is a difference of two hours in local time between the easternmost part of Arunachal Pradesh and, the westernmost part of Gujarat.


Solution
 The Arunachal Pradesh is the easternmost state and the Gujarat is the westernmost state. Naturally, they experience such variation in the local time because of the longitudinal distance of 30° longitudes. This longitudinal distance of 30° longitudes makes a difference of 2 hours between the Arunachal Pradesh and the Gujarat. Hence, when it is 6 a.m. in Arunachal Pradesh, the local time at Gujarat is supposed to be behind by 2 hours as compared to the Arunachal Pradesh, it is 4 a.m. Therefore, it is correct to say that when the sun has already risen in the Arunachal Pradesh, it is still night in the Gujarat.
