Answer 2

Answer:

The time difference between GMT & IST is 5.30 Hours. The Sun rises from east and sets in the west. This apparent movement is caused by rotation of earth from west to east. Kolkata is on East side and Mumbai is on West side

According to the Indian Standard Time for IST theory , the time difference of Mumbai and Kolkata is null. But this time is counted on an average basis.

To calculate the real difference of the local time of Mumbai and Kolkata we must apply the GMT theory.

The longitudes of Mumbai and Kolkata are,(72°54' E) & (88°24' E).

So the total longitudinal difference of these two cities are,

=(88°24' - 72°54')

= 15°30'

According to the GMT theory,4 minutes of time difference is occurred for 1° longitudinal distance.

So the actual local time difference between mumbai and kolkata is (15°30'X4) = 62 minutes

If the local time of Mumbai is 3 p.m.

The actual local time of Kolkata will be 4:02 p.m
