Your uncle buys a new car that comes with seven new tires, one for each wheel, and three spares. He decides to be economical by using the three spares as much as the other four. If he drives 22, 750 miles and each tire has been used equally, what will be the wear in miles on each tire?
i think that you would just divide by seven, but i feel that is too easy.
can anyone please help?
