Question

If it is currently 10 am for the locations on this map, what would be the approximate local time in Paris, France (50°N, 0°)? Explain how you figured out this time.

a) 3 pm; Considering the time difference between the locations.
b) 10 am; Paris is at the same longitude as the reference location.
c) 6 pm; Paris is ahead of the reference location in terms of time.
d) 12 pm; Paris is behind the reference location in terms of time.

Answer 1

The local time in Paris, France, is 10 am if it is also 10 am in a reference location on the Prime Meridian, since both are located at 0° longitude.Option B is the correct answer.

Step-by-step explanation:

To determine the local time in Paris, France, when it's 10 am in a reference location, we need to consider the difference in longitude between Paris (50°N, 0°) and the reference point.

Since each 15° of longitude represents one hour difference in time, with east being ahead, we can apply this knowledge to our problem. The longitude of Paris (0°) lies on the Prime Meridian, which is used as the starting point for Universal Time (UTC).

As such, if it is 10 am at a reference location on the Prime Meridian, then the local time in Paris will be the same, 10 am, because Paris is at the same longitude as the reference location. Therefore, the correct answer is b) 10 am; Paris is at the same longitude as the reference location.
