WHAT IS THE LONGITUDE OF TOWN X WHOSE TIME IS 12;00 NOON WHEN GREENWISH MEANS TIME IS 6;00PM

So Greenwich, (not Greenwish), is 6 hours ahead of the town

so the town must be at 90° West, or -90°
(I am in that time zone)

To determine the longitude of a town based on its time difference from Greenwich Mean Time (GMT), you can use the concept of time zones. Every 15 degrees of longitude represents an hour of time difference.

In this case, we have a time difference of 6 hours between Town X and Greenwich Mean Time. So, to find the longitude of Town X, we need to calculate how many 15-degree intervals make up a 6-hour difference.

Since every hour represents 15 degrees, 6 hours would represent 6 times 15 degrees, which equals 90 degrees.

Therefore, the longitude of Town X is 90 degrees west of the Prime Meridian (0 degrees longitude), as it is 6 hours behind Greenwich Mean Time.

Note: We assume that the time difference is a whole number of hours and that the time in Town X is calculated based on a 24-hour clock.
