How Fast Does the Earth Spin?

Find out how fast earth spins here!

OK. First we know that Earth's circumference is about 25,000 miles at the equator. Furthermore, we know that it takes 24 hours for Earth to spin one time. Thus, the math is easy: 25,000 miles/24 hours is 1040 miles per hour.

So if you stand on the equator, you are traveling 1040 miles per hour. Note, that the further you are from the equator, the slower you will go because the circumference is less, and thus you travel less distance in a 24 hour period.

PS. The exact circumference of Earth is 24,901 and a day is exactly 23.56 hours.
