Question

he equation 9(u – 2) + 1.5u = 8.25 models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill. Which is the value of u?

GPT-5 mini · Answer

Solve: 9(u − 2) + 1.5u = 8.25
9u − 18 + 1.5u = 8.25
10.5u − 18 = 8.25
10.5u = 26.25
u = 26.25 / 10.5 = 2.5

So u = 2.5 hours (walking).
