Question

Determine the number of full rotations the tires of each of the vehicles will complete in 10,000 miles.

I have a graph here that shows the circumference of each tire.

Answer 1

Total number of rotations that will be needed for the car to complete 10000 miles will be given by:
rotations=(distance)/(circumference)=10000/(86.4×1.57828×10^-5)
=7333346.475 rotations
