silly, simple, spinning math

I rebuilt the 33ft open test track this week and have been racing LOTS of cars. I raised the starting ramp height by 2" to give the cars a chance to complete the coarse @ higher speeds. Most cars have been averaging 3.5sec on the hybrid road coarse and my fastest cars can run it in less than 3sec. While witnessing these cars @ speed, I began to wonder "Exactly how fast do these wheels spin?"...so I got out my ruler & calculator.

As an example, I'll use this car:

(106.7 x 60 = 6402) .....

Kinda cool, eh?
