Once every 24 hours.
-
On its own axis, at the equator, it's 1 revolution = 25000 miles per day; So that's a little more than 1000 miles per hour

It should be noted that the earth speed is not the same all over the globe; in fact the earth's speed can vary depending on the distance from the equator to the poles. For instance, the earth's speed is fastest at the equator- where the circumference has the most distance to travel around the axis. At the equator, the earth spins at 1,038 mph, as stated above, however if you are directly on the North or South Pole, the distance for the earth to revolve around the axis is practically zero meaning that the earth's speed is extremely slow. In fact, the earth's speed at the North or South Pole is about one centimeter per 24 hour period.

The speed of rotation of earth around it's axis is fastest at the equator and almost 0 at the poles. The speed of rotation at the equator is around 1669.8 km/hour while that around the sun is 107278.87 km/hour.

Obviously something near the poles would move a lot slower than something at the equator, but given that it has an equatorial circumference of ~40000 km, rotates once every 24 hours the speed of something at the circumference is approximately 1,666 kph
