It depends on where you're standing! Sort of like on a merry-go-round. If you stand near the merry-go-round's center, you'll go fairly slowly. If you stand near the merry-go-round's edge, you'll go fairly fast.
Likewise, if you're near the north or south pole, your speed is slow, and if you're near the equator, your speed is much faster. And in between, it varies.
At the equator, your speed is about 1000 mph. At other latitudes, you need to multiply that by a factor called "cosine" that takes the latitude into account:
speed = 1000 mph x cos(latitude)
At a latitude of 40° (about through the middle of the U.S.), the speed is about 800 mph.

It varies as a trigonometric function of latitude. At the equator, it's about 1,040 MPH, while at 45 degrees latitute (N or S), it's about 730 MPH.

2*pi*6400/24 gives you the answer in km per hour then divide by 1.6 to get the answer in mph.

1015 miles per hour at the equator.
