Answer:

Small tire, 9in ----> 127 rotations

Big tire, 30in ------> 38 rotations

Step-by-step explanation:

First, we convert the values of feet to inches

600 feet = 7200 in

Each rotation of a tire is equivalent to a traveled distance equal to the perimeter

P = 2*pi*radius

This means that if we divide the traveled distance by the perimeter of each tire, we can find out the number of rotations.

Small tire, 9in

7200 in / 2*pi*9in = 127 rotations

Big tire, 30in

7200 in / 2*pi*30in = 38 rotations
