Indian Standard Time and Greenwich Mean Time

Indian Standard Time (IST) and Greenwich Mean Time (GMT) are two different time standards used in different parts of the world. IST is the time standard used in India, while GMT is the time standard used at the Prime Meridian, located in Greenwich, London.

Time Difference

The time difference between IST and GMT is determined by the geographical distance between India and London, and the rotation of the Earth. India is located to the east of the Prime Meridian, which means that as one moves from west to east, the time gets ahead.

Explanation of the Correct Answer

The correct answer to the question is option 'C', which states that Indian Standard Time is ahead of Greenwich Mean Time by 5 hours and 30 minutes. Here's the explanation behind this answer:

1. IST and GMT Comparison
- Indian Standard Time (IST) is the time standard used in India.
- Greenwich Mean Time (GMT) is the time standard used at the Prime Meridian in Greenwich, London.

2. Geographical Location
- India is located to the east of the Prime Meridian.
- The Prime Meridian is considered as the starting point for time zones and is assigned a time of 0 hours.
- As one moves east from the Prime Meridian, the time increases.

3. Time Difference
- The time difference between IST and GMT is determined by the geographical distance between India and London.
- India is approximately 5 hours and 30 minutes ahead of London.
- Therefore, Indian Standard Time is 5 hours and 30 minutes ahead of Greenwich Mean Time.

Conclusion

In conclusion, Indian Standard Time (IST) is indeed ahead of Greenwich Mean Time (GMT) by 5 hours and 30 minutes. This time difference is a result of India's geographical location to the east of the Prime Meridian. Understanding the time difference between different time zones is essential for coordinating international activities, travel, and communication.
