The answer depends on whether you mean 15 degrees on a clock face (0.5 hours) or 15 degrees of longitude (1 hour).
Neptune has an uneven rotation that varies between 12 to 18 hours. I will use 15 hours as a midpoint. Neptune has 360 degrees total. Divide that by 15 and you get 24 degrees per hour. Multiply 24 by 3 and you get 72 degrees. So, based on 15 hour rotation time, Neptune will spin 72 degrees in just 3 hours.
7.5 degrees per hour
7.5 degrees per hour.
On an ordinary clock, with 12 hours on the face, the hour hand rotates360 degrees in 12 hours30 degrees in 1 hour = 60 minutes1/2 degree per minute5 degrees in 10 minutes
131,490 hours.
15 degrees
That would be 15 degrees---360 divided by 24 hours
It rotated 15 degrees, because 360 divided by 24 is 15, and 15 times 3 is 45.

There are 15 degrees of longitude in each timezone, because there are 360 degrees of longitude and 24 hours a day, so 360/24 is 15.
There are fifteen (15) degrees of longitude per time zone. (15 degrees x 24 zones = 360 degrees around the planet)
The sun appears to move 15 degrees in a one hour. However, it is really the Earth that rotates 15 degrees an hour, relative to the sun.15 degrees. (This is APPARENT motion only. The Earth is revolving. The Earth takes 24 hours to revolve 360 degrees.) 360 degrees/24 hours x 1 hour = 15 degrees
1 revolution / 24 hours = 360 degrees / 24 hours = 15 degrees per hour
360 degrees divided by 24 = 15 degrees
360 degrees in 24 hours means 15 degrees per hour.
The Earth rotates every 23h56m; rounding this to 24 hours, you have a full rotation, or 360 degrees, every 24 hours. This is equal to 15 degrees per hour.The Earth rotates every 23h56m; rounding this to 24 hours, you have a full rotation, or 360 degrees, every 24 hours.
