Question

150 cookies in 3 hours equles how may cookies per hour?

Answer 1

50 cookies per hour

Explanation

to find the unit rate ( cookies per hour) just divide the total of cookies by the number of hours

$\text{unit rate=}\frac{total\text{ cookies}}{\text{total time}}$

Step 1

Let

total cookies=150

total hours=3

now, replace

$\begin{gathered} \text{unit rate=}\frac{total\text{ cookies}}{\text{total time}} \\ \text{unit rate}=\frac{150\text{ cookies}}{3\text{ hours}} \\ \text{unit rate}=50\frac{\text{ cookies}}{hour} \\ \text{unit rate}=50\text{ cookies per hour} \end{gathered}$

I hope this helps you.
