Asked by Rezu
Betty and Tracy planned a 5000km trip in an automobile with five tires, of which four are in use at any time. They plan to interchange them so that each tire is used the same number of kilometers. What is the number of kilometers each tire will be used?
I don't get this question. Can anyone help?

I can see two ways of solving this problem.
5,000 / 5 = 1,000
4 * 1,000 = 4,000 km
or
Each tire will be used 80% of the trip.
0.8 * 5,000 = 4,000
5,000 / 5 = 1,000
4 * 1,000 = 4,000 km
or
Each tire will be used 80% of the trip.
0.8 * 5,000 = 4,000
