its easy to calculate.
earth complete one revolution arond its axis in 1 day.
its radius is 6400km
hence covers a distance of 40192km ( circumfrence when taken from 1 point) per day.
so 40192/24
equals 1674.66km/hr
HOPE U R SATISFIED

That depends on where on Earth you are standing. At the poles, the Earth hardly spins at all, but as you travel towards the equator, the rotational speed picks up. This makes sense -- as the circumference of a circle increases, a single point along it has to travel faster to complete a revolution in the same amount of time.
The rotational speed of the Earth at the equator is about 1,038 miles per hour. The atmosphere at the equator is also slightly thicker due to rotation, and you weigh slightly less. At mid-latitudes, the speed of the Earth's rotation decreases to 700 to 900 miles per hour.
If the Earth were to stop spinning suddenly, the atmosphere would still be zipping along nicely at around 1,000 miles an hour. As a result, everything not attached to bedrock would pretty much be scoured clean.

The rate of spin if measured at the equator is about a 1/4 mile per second.

The speed at which the earth spins varies upon your latitudinal location on the planet. If you're standing at the north pole, the speed is almost zero but at the equator, where the circumference of the earth is greatest, the speed is about 1,038 miles per hour (1,670 kph). The mid-latitudes of the U.S. and Europe speed along at 700 to 900 mph (1125 to 1450 kph).

Well it takes the earth a full day to spin 360 degrees so i am guessing it is not that fast.

The circumference of the earth at the equator is 24,902 Divided by 24 hours in a day equals 1037.58 mph.

At the poles, the speed of Earth's rotation is almost 0 miles per hour. At the equator, it is around 1000 miles per hour. Anywhere in between is slower than 1000 miles per hour but faster than 0 miles per hour.

It makes a full revolution in about 24 hours, and it is 25,000 miles or so in girth at the equator, so the spin is 25,000/24. That is over 1000 miles per hour.

Earth make 1 revolution in 86400 seconds
Equatorial Radius R = 6,378,000 meters
Circumference C = 2*pi*R = 40,090,285 meters
Equatorial Tangential Speed = C/86400 sec = 464 m/sec
or 1670.4 kph
