  Isn't this laughably simple to calculate?

  3500 rpm = 3500*60 rph, and in 1 hour it travels 75 miles. Thus divide
75 miles by 3500*60 revolutions, and you have the amount of miles per one
revolution, which would be approximately 0.0003571428 miles.

  Given that I'm not sure which whacky units miles are divided into,
I'll just convert those to more understandable units, so 75/(3500*60)
miles is approximately 57.5 centimeters.
