Earth rotates at how many degrees per hour?

Explanation:
The rotation rate is defined by how long it takes Earth to complete one full turn. It makes a 360-degree rotation in 24 hours, so it turns 360 ÷ 24 = 15 degrees per hour. That also means one degree corresponds to four minutes of time, which helps relate time differences to longitude. Among the options, 15 degrees per hour is the correct rate, since the other numbers would imply a day longer or shorter than 24 hours and don’t match how the Earth actually rotates.
