Question

the sun rises two hours earlier in arucachal Pradesh as compared Gujrat in the west but the watches show the same time. how does this happen
lesson of geography​

Answer 1

Explanation:

From Gujarat to Arunachal Pradesh there is a time lag of two hours, but the watches show the same time because the time along the Standard Meridian of India (82° 30' E) passing through Mirzapur in Uttar Pradesh is taken as the standard time for the whole country.

Answer 2

Traveling from east to west the time gap between each latitude is 2 minutes.

So there is 2 hours gap between Arunachal Pradesh and Gujarat.

To avoid confusion every country has a standard meridian

It is another story

In each time zone there are 7 1/2 latitude

The exact middle latitude must be taken as standard meridian of the particular time zone

For IST zone it is 82 1/2 ° E

It is 5.30+ hours from Prime meridian

So every watch in our country shows this time
