Question

The time of India is ahead of that of England by
(a) 2 hours
(b) 5 hours and 30 minutes
(c) 3 hours
(d) none of these

Answer 1

(b) 5 hours and 30 minutes

Explanation:

Earth has 24 time zones of one hour each. Each zone has 15 degrees of longitude. The longitude of 82.5 degrees east is considered as Indian Standard Meridian and the time of this meridian is Indian Standard Time. The Greenwich Mean Time refers to the time at Prime Meridian.

The time difference can be calculated as :

The difference between 0° longitude and 82.5° E longitude is 82.5°.

Time in the east is ahead by 4° per meridian.

Hence  time ahead will be

$82.5\times 4=330 \ minutes=5.30\ hours$.

Hence Indian time is ahead by 5.30 hours.

Answer 2

Answer:

The time of India is ahead of that of England by 5 hours and 30 minutes.

Explanation:

India is ahead of England by 5 hours and 30 minutes.

The Earth, being a huge planet, has 24 time zones panned across its surface, with the value of 1 hour each. Each zone is bounded by a 15 degrees in longitude.

The longitude mapped at 82.5 degrees E is considered as the Indian Standard Meridian, which gives us the Indian Standard Time.

The Greenwich Meridian, on the other hand, gives us the Greenwich Mean Time, at 0^0.

The time difference, thus, can be calculated as follows -

We first calculate the difference in the longitudes - 82.5^0

With each meridian in the East, the time is ahead by 4 minutes.

Thus, 82.5 x4 = 330 minutes = 5.5 hours

Thus, the time difference between England and India is 5 hours and 30 minutes.
