Answer 1

Answer:

82°30' E

Explanation:

The longitude 82°30' E (which passes through Mirzapur) has been selected as the standard meridian of India.

Two reasons for its selection are:

• This longitude passes through Mirzapur and divides India into almost equal eastern and western parts. India is a vast country and have a great difference in sunrise timing along East in Gujarat and West in Arunachal Pradesh. This longitude ensures same timing all over India.
• Vast countries such as Russia ,  China , etc. have more than one time zones. If we move from one time zone to the other we have to change our clocks' time accordingly to ensure proper time. The single time zone of India gives us same time all over India thus reducing inconvenient method of changing time.
