We can find the unit rate as follows:
We can divide 3/8 by 1/6, and it will give us the unit rate by an hour:
[tex]\frac{\frac{3}{8}}{\frac{1}{6}}=\frac{3\cdot6}{8\cdot1}=\frac{18}{8}=\frac{9}{4}=2.25[/tex]Therefore, the unit rate is 2.25 ft^2/hour.
We need to remember that a unit rate is a rate with a unit in the denominator, in this case, one hour (or per hour).
