The Captain of a ship recorded the time as 7.00 hours GMT when the sun was exactly overhead. Where was the ship stationed ?

(A) Indonesia

(B) India

(C) Sri Lanka

(D) (Bangladesh)

Answer- (A) Indonesia

Explanation -:

Since the sun was exactly overhead, the ship must have been located on the Earth’s equator, where the sun’s rays strike the Earth directly at noon.

To determine the ship’s longitude, we need to consider the time difference between the ship’s location and Greenwich Mean Time (GMT).

The Earth takes 24 hours to complete one rotation, and it has 360° of longitude. Therefore, each hour of time difference corresponds to 15° of longitude (360° / 24 hours = 15° per hour).

Since the ship’s time was 7:00 hours GMT, and the sun was overhead, the ship must have been located at a longitude where the local time was 12:00 noon.

Assuming the ship was on the equator, we can calculate its longitude as follows:

GMT 7:00 hours = 7 hours ahead of GMT
7 hours x 15° per hour = 105° East longitude

Therefore, the ship was stationed at a location with a longitude of approximately 105° East, on the equator.

Indonesia: Coordinates – 0.7893° S, 113.9213° E

India : Coordinates -20.5937° N, 78.9629° E

Sri Lanka Coordinates – 7.8731° N, 80.7718° E

Bangladesh Coordinates : – 23.6850° N, 90.3563° E

Based on the longitude of 105° East, the correct answer is: Indonesia
