Answer 2

Answer:

The local time at Mumbai, when Greenwich mean time is 12noon = 4.52 PM

Explanation:

To find,

The local time at Mumbai - 73 degrees east - when Greenwich mean time is 12noon

Recall the concept:

Greenwich Mean Time is located at 0° longitude.

When we move towards the east of GMT, the time increases and it takes 4 minutes to cross 1° longitude.

1° = 4 minutes

73°  = 73×4 = 292minutes

Since 60 minutes = 1 hour

292 minutes = 4 hours and 52minutes

Since when we move towards the east of GMT, the time increases,

the local time at 73 degrees east = 12 + 4hours 52 minutes

= 16.52 hours

= 4.52 PM

∴ The local time at Mumbai, when Greenwich mean time is 12noon = 4.52 PM
