Question

The sun rises two hours before in Arunachal Pradesh than in the Rann of Kuchch,

Gujarat but the clocks and watches show the same time. Comment

Answer 1

In turning 360 degrees the earth covers 24 hours. ie. it covers 1 degree in 4 minutes
the latitudinal difference between Arunachal Pradesh and Gujarat is 30 degree.
ie there is two hour difference between the places
however the time in clocks is calculated with respect to the Indian standard meridian located at 82.5 degree East.

Answer 2

The longitudinal gap between Arunachal Pradesh and Gujarat is about 30°. Due to this, there is time lag of about two hours between these states. Since Arunachal Pradesh is in the east hence the sun rises earlier here compared to in Gujarat. The Indian Standard Time is taken from the time of Standard Meridian of India and hence, the watches show the same time in both the states.☺️
