Question

why is 82.5 longitude taken as the standard meridian of india

Answer 1

Explanation:

This is because India has a wide east-west extent making it difficult to select the longitudes at the eastern or western ends as Standard meridians as this would lead to serious discrepancies between the time followed and the sun’s position in the sky. To avoid such difficulty and to have a uniform time across the country 82 30 E has been chosen as the Standard Meridian as it passes through the middle of India reducing such difference.

Answer 2

Answer:

82 degrees 30 minutes is selected as the standard meridian because it lies almost in the centre of India.
