How slow does the earth spin?
Answer 1:

The Earth spins once every 24 hours. The Earth is 40,000 km in circumference. That means that, at the equator, the Earth spins at roughly 1,600 kilometers per hour, or about 1,000 miles per hour. This is about twice as fast as a commercial airline jet.

At the pole, however, the Earth isn't actually moving at all.
