First, figure out the rotational velocity of the earth in radians/hour. It is a simple unit conversion. Given, 1 revolution/day.

Second, figure out the distance from the center of the earth for Idianapolis using trig. The earth's radius at the equator is 3963 miles, and it lies at a latitude north of the equator at 39.769 degrees.

Third, multiply the the two and get 797 mph.

About 700 mph, not sure if that is magnitude, but it's the speed.
