The 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?

Eliminating parentheses gives
10.5u -18 = 8.25
10.5u = 26.25
u = 2.5

The value of u is 2.5.

What fun! Michael spent 2.5 hours walking up the hill for 0.5 hour of time sledding down.
