### Instruction: The earth rotates at a constant rate and rotates 360 degrees in one day. How many degrees does it rotate in one hour?### Response: To solve this problem, I need to find the rate of rotation in degrees per hour.
I know that one day has 24 hours, so I can divide 360 degrees by 24 hours to get the rate.
Using a calculator, I get 360/24 = 15 degrees per hour.
This means that the earth rotates 15 degrees every hour.
