15 degrees of longitude equals one hour.

However, for national convenience e.g. the USA , there are four time zones . This covers longitudes 70 o W to 125 o W. a difference of 55 degrees. This does not fully cover 4 hours of longitude, but is done for national convenience, into Eastern, Central, Mountain and Western. , lenpollock

You are awesomely wrong!

The above is true for longitude, not latitude. The tilt of the earth's axis is approx 23Â° and over the course of a year, the midday sun appears to move from being overhead at the Tropic of Cancer (Midsummer in the northern hemisphere) to the Tropic of Capricorn (Midwinter) and back again. So, the average speed is 0.0107 degrees per hour. However, in fact the speed follows a sine curve and so depends on the time of the year.   Wiki User

60 degrees

Each turn of the Earth = 24 hours = 360o

Therefore each hour is 15o

(360 degrees per rotation) / (24 hours per rotation) = 15 degrees per hour   Wiki User

There are 360 degrees of longitude on Earth and 24 hours a day, so one hour corresponds to 360/24 degrees, which is 15 degrees longitude.   Wiki User

Since there are 60 minutes in one degree, and 60 seconds in one minute, there are 3,600 seconds in one degree of latitude !   Wiki User

1 revolution / 24 hours = 360 degrees / 24 hours = 15 degrees per hour   Wiki User
