Trad said "So the earth spinning at 1,000 mph (faster than the speed of sound) is not the same as spinning a basketball at 1,000 mph? The speeds are the same. Also how does the fact if one moved north or south of the equator on the fictitious rotating globe his speed would decrease until it reached zero at the north or south pole? Why doesn't that person feel the change in speed? Hint; he doesn't because we experience a flat and unmoving earth."
You do realise that the speed can only apply to a POINT on the Earth, don't you?
You can work out the circumference of a circle from first principles, I assume? And you accept that circles drawn at the equator will have different circumferences than circles drawn partway up a globe?
If you slice a tennis ball at its widest point, and another a quarter of the way down, you'll get different-sized circles at the cut point, won't you?
Honestly, there's enough clues here. You've got to take the rotational speed in revolutions per minute, hour, day, whatever, and apply that to the distance travelled by a point on the surface.
