As pointed out to me by Dr. Chu of the Astronomy Department at the U. of Illinois at Urbana-Champaign, this value isn't quite right.

She's correct: the earth is revolving at approximately 1030 miles per hour at its equator, and at 900 miles per hour only at a latitude of ~29 degrees (north or south). The closer you get to either pole, the less distance the earth needs to spin to complete one revolution, and so the slower it rotates.

Hmm, I wonder if the other numbers are any more accurate...
