Try to solve this math riddle!?

[PandaLove1]

The tip of a blade on an electric fan is 1.5 feet from the axis of rotation. If the fan spins at a full rate of 1760 revolutions per minute, how many miles will a point at the tip of a blade travel in one hour?

This seemed to be a question that tricked people alot. It's from a Coloraldo Elementary Math Textbook, yet fumbles adults. Can you solve it? Whoever solves it first with all the steps (i.e. show work) wins 10 points!

Distance per revolution = 2.Pi.r = 2 x [22/7] x 1.5 = 9.42857
Distance in one hour = 1760 x 60 x 9.42857 = 995,656,992 ft = 188.57miles
