A 12-inch wheel has a diameter of 12 inches, which is 1 foot. The circumference of the wheel is π (pi) times the diameter, or π feet. A mile is 5,280 feet, so the 12-inch wheel must turn 5280/π or about 1,680.676 times.
Since it'll be rolling around the outside of the circle, the distance traveled will be in some multiple of the circumference. So, dividing the distance by the circumference will give the answer. C = πD = 6π revolutions = distance / circumference = 108π / 6π = 18 revolutions
Two complete revolutions.
0.33 revolutions.

To find the time in minutes that the wheel rotated, divide the total number of revolutions by the revolutions per minute (RPM). Time (in minutes) = Total Revolutions / RPM = 205 revolutions / 16.37 RPM ≈ 12.54 minutes. Thus, the wheel rotated for approximately 12.54 minutes.

The revolutions per minute of a bike wheel depends on the size of the wheel, the speed you are riding, and other factors. It is generally thought it can spin at 2 revolutions per second.
