If the local time at a place X is 12.00 noon when the G.M.T is 5.00a.m then X is located on longitude

To determine the longitude of place X, we need to understand the relationship between time and longitude. The Earth is divided into 360 degrees of longitude, and it completes one full rotation (360 degrees) in 24 hours. Therefore, for every hour, the Earth rotates 15 degrees of longitude.

The given information is this:

• Greenwich Mean Time (GMT) is 5:00 a.m.
• Local time at place X is 12:00 noon.

The difference in time between GMT and the local time at place X is 7 hours (from 5:00 a.m. to 12:00 noon).

Calculation:

• For each hour, there is a 15-degree difference in longitude.
• Therefore, a 7-hour difference corresponds to 7 hours × 15 degrees/hour = 105 degrees.

Now, we need to determine whether place X is east or west of the Prime Meridian (0° longitude, the reference line for GMT).

- Since the local time at place X is ahead of GMT (12:00 noon compared to 5:00 a.m.), it means X is east of the Prime Meridian.

Thus, place X is located on 105°E.
