Answer 1

the rate in minutes per mile is;

`10\text{ minutes per mile}`

Step-by-step explanation:

Given the table in the attached image.

For Marta , she travelled 8 miles in 80 minutes;

`\begin{gathered} \text{distance d = 8 miles} \\ \text{Time t = 80 minutes} \end{gathered}`

The rate r in minutes per mile will be;

`\begin{gathered} r=\frac{\text{time t}}{\text{distance d}}=\frac{80\text{ minutes}}{\text{8 miles}} \\ r=10\text{ minutes/mile} \end{gathered}`

Therefore, the rate in minutes per mile is;

`10\text{ minutes per mile}`
