24/8 = 3 minutes per problem
54/3 = 18 problems in 54 minutes
Another way to solve this problem is to set up a proportion. Cross multiply and solve for x.
8/24 = x/54
24x = 432
x = 432/24
x = 18

C.because it takes 3 min per problem which equal out to 8 problem in 24 min and in 54 min you can solve 18.
