answer a. 12 times 14 give us 168 minutes.

answer b. 42/14 = 3 tires

Step-by-step explanation:

You can do this problem a couple of ways.

Since we have two different forms of problems, let's solve for per minute of each tire.

a. 56/4 gives us time per tire in minutes.

14 minutes per tire

3 vans have 12 tires.

answer a. 12 x 14 give us 168 minutes.

b.

divide 42 minutes by 14 minutes to see how many tires he can fit.

answer b. 42/14 = 3 tires
