When a wheel rolls along, the number of times it completes a full revolution to cover a certain distance varies inversely as the circumference of the wheel

When a wheel rolls along, the number of times it completes a full revolution to cover a certain

distance varies inversely as the circumference of the wheel. If the wheels on a car have a

circumference of 80 inches and they make 400 revolutions in traveling a certain distance:

a) Find the constant of variation, k.

b) show an equation relating the number of revolutions made by a wheel to its

circumference in centimeters for this particular distance.

c) If a wheel has a circumference of 95 inches, how many revolutions will it make?
