24 hours
1 revolution / 24 hours = 360 degrees / 24 hours = 15 degrees per hour
A polar view of the planet is roughly circular, that is, a total 360 degrees. There are about 24 hours in each day. Divide 360 by 24; the answer is 15, so there are 15 degrees of longitude in each time zone.
There are fifteen (15) degrees of longitude per time zone. (15 degrees x 24 zones = 360 degrees around the planet)
If it's noon solar time at 90 degrees W longitude, every 15 degrees of longitude represents a one-hour time difference. So, at 72 degrees W longitude, the solar time would be 2 hours behind (2:00 PM).
If a day had 36 hours instead of 24, each time zone would cover 30 degrees of longitude instead of the current 15 degrees. This is because the Earth rotates 360 degrees in 24 hours, so with 36 hours in a day, each hour of difference would correspond to 30 degrees of longitude.
The time difference between the local time and Greenwich Mean Time (GMT) is 2 hours. Since there are 360 degrees of longitude in a full circle and 24 hours in a day, each hour of time difference corresponds to 15 degrees of longitude. Therefore, the longitude of the town would be 30 degrees west of the Prime Meridian (Greenwich).
A time zone typically spans 15 degrees of longitude, as there are 24 hours in a day and 360 degrees of longitude around the Earth. This means each time zone covers four meridians, one for each hour.
the earth is divided into 24 time zones, each 15 degrees of longitude in width. Since earth rotates once every 24 hours on its axis and there are 360 degrees of , each hour of Earth rotation represents 15 degrees of longitude.
There are 15 degrees of longitude in each standard time zone
Every latitude extends all the way around the Earth, and is unrelated to the time at any place.If you were to consider longitude instead, the difference in solar time between two longitudes is(longitude #1)degrees minus (longitude #2)degrees/15 hours.
If the chronometer reads 8 AM Pacific Standard Time at solar noon, it indicates that your location is 120 degrees west longitude. This discrepancy in time suggests that you are 2 hours away from the Pacific Time Zone (120 degrees west longitude corresponds to a 2-hour time difference from Pacific Time).
The Earth rotates at the rate of roughly 15 degrees of longitude per hour.
