Number of degrees of longitude for one hour's time?

Answer 1

15. There are 24 hours; a full rotation is 360, so 360 divided by 24 is 15.
The earth spins approximately 360 degrees in twenty four hours (one day).
The earth spins 15 degrees in one hour. _____________ The above is correct in a general sense, but this is a little more complex than meets the eye. The earth spins very close to what might be called 15 'synodic' degrees in one hour, if you are dealing with coordinate degrees of longitude relative to the sun. But since the earth spins more than 360 sidereal (or absolute) degrees in 24 hours, the number of sidereal degrees per hour must be slightly greater than 15, since slightly less time (sidereal day) amounts to 360 absolute degrees. The sidereal day is about 23.93447232 hours. The earth spins 360 absolute degrees in this period of time. This yields roughly 15.041 degrees of sidereal spin per hour.
15 degrees

Answer 2

The sun appears to move 360 degrees in 24 hours and so 360/24 = 15 deg each hour.

Answer 3

Since we define one complete rotation as 24 hours and also define it as 360 degrees,

1 hour = (360 / 24) = 15 degrees.

Answer 4

The earth rotates at a rate of 15° per hour.

By a remarkable coincidence, that works out to 360 degrees in 24 hours.

Answer 5

I think almost everyone will agree that the Earth turns 360 degrees in 24 hours.

That boils down to a unit rate of 360/24 = 15degrees per hour.

Answer 6

There are 15 degrees of longitude for each hour's time change, as the Earth rotates 360 degrees in 24 hours. Therefore, dividing 360 by 24 gives 15 degrees per hour.

Answer 7

1 hour = 15 degrees of longitude

Answer 8

.25 degrees

Answer 9

5 degrees
