What is the time difference between meridians of longitude?

Question

Help me, please.

Answer 1

Fred is right, though I would say that it is 15 deg per hour.

From there you get 0.25 deg / min, or, 4 minutes per degree of longitude

Answer 2

If there are infinite points on a circle, there are infinite meridians of longitude, on planes perpendicular to the plane of the equator.

But let's assume you mean a meridian that marks another degree of latitude from the accepted zero point. That is, of course, the Prime Meridian that used to run through the cross hairs of the spiffiest telescope at the Royal Observatory in Greenwich, England, but which now runs a little bit east of there by my GPS receiver.

The general rule gives 15 degrees of longitude for every hour's difference in the time zone. The truth is, though, that time zones are political constructs, built more on the borders of nations and the location of population centers than longitude. For example, most of Indiana is in the Eastern time zone, but a chunk of Indiana is in the Central time zone. That chunk has suburbs of Chicago such as Gary, Indiana. With many residents that work in Chicago, it makes sense for those suburbs to be on the same time zone as Chicago.

Another important example is China, which has the same official time zone for about 60 degrees of longitude, though the Xinjiang Uygur Zizhiqu in China's far west ignores Beijing on the issue of time zone. People there tend to keep their watches set about two hours behind China time.

Answer 3

360 degrees
24 time zones

360/24 deg per time zone. = 15 deg/zone

Answer 4

1 hour, 24 of them make up the time zones, if I understand what you may be asking.

Answer 5

oh for petes sake people keep it simple - 15 degrees per hour - the asker can take it from there if they want finer or courser measurements.
