Asked by Nina

One tire has a diameter of 7 in and another has a diameter of 12 in. What is the difference in the distance the tires make in two revolutions?
I don't get the question could you explain?
Answered by Steve
the circumference of the tire is the distance it moves in one revolution.

So, what are the circumferences of the two tires?

You want the difference, times 2 (for two revolutions)
