Asked by James

In a certain gear, a bicycle tire with a diameter of 27 inches makes 3 complete revolution of the pedal.If a cyclist is pedaling at a rate of 100 revolutions per minute, find the speed of the bicycle in miles per hour?
Answered by Steve
Assuming you meant

<u>a bicycle tire makes 3 complete revolutions for each revolution of the pedal</u>

then we have (in inches/minute)

100 * 3 * 27π

Now just convert that to miles/hour.
