Asked by Bob
                The wheels of a moving bicycle have 27-inch diameters, and they are spinning at 200 revolutions per minute. How fast is the bike traveling in miles per hour? 
27*π*200=16964.6
1mi=63360in 63360/16964.6=3.73
I am not sure if i did it right

    You figured out miles per minute, not mph, right?

    You figured out min/mile. Keep track of the units!
16964.6 in/min * 1mi/63360in = 0.2677 mi/min
Now multiply that by 60min/hr to get mi/hr.
