If a ship is sailing on an ocean and it is 2:00 pm at the prime meridian and 10:00 am on the ship, what is the longitudinal location of the ship? [Hint:longitude can be only E or W]

To determine, if a ship is sailing on an ocean and it is 2:00 pm at the prime meridian and 10:00 am on the ship, what is the longitudinal location of the ship, the following logical reasoning must be performed:

The time zones move across the world map from left to right, that is, from west to east. Thus, the west will always be a smaller time zone than the east.

Therefore, if it is 2 PM (14:00) at the prime meridian and 10 AM on the ship, the ship is west of the prime meridian.

The longitude of the location of the ship is W

Explanation:

Here we have the time at the prime meridian as 2 pm while the time at the ship is 10 am

What this means is that the prime meridian is 4 hours ahead of the time of the location of the ship.

Geographically, whenever a location is east of the prime meridian, it is ahead of the prime

meridian on time

If however a location is west of the prime meridian, the prime meridian is ahead of it on time

In this question, we can see that the prime meridian is ahead in time, so automatically the location is west of the prime

meridian

So therefore, its longitude is W
