Ilia_Sergeevich [38]

we know that

<u>Unit Rate</u> is the ratio of two measurements in which the second term is one

to find the unit rate divide $(5/8)$ by $(1/4)$

$Unit\ rate=\frac{(5/8)}{(1/4)}= \frac{5}{8}*4= \frac{2.5}{1} =2.5 \frac{ft^{2}}{hour}$

therefore

<u>the answer is</u>

The unit rate is $2.5 \frac{ft^{2}}{hour}$
