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
