Question

what would happen to the number of the rotation if the circumference of the tire were to decrease by 20%

Answer 1

per rotation is 10,000miles

Answer 2

I assume that there is a constant distance to be covered.

the number of rotations is d/C where C is the circumference of the tire.
so, d/(1.2C) = 1/1.2 * d/C
The number of rotations would be divided by 1.2

Answer 3
