Question: 1 / 400

A jogger runs 4 miles in 32 minutes. What is their average speed in miles per hour?

6 mph

7.5 mph

To find the average speed of the jogger in miles per hour, we start by calculating the total number of hours taken to run the distance. The jogger runs 4 miles in 32 minutes. Since speed is generally expressed in miles per hour, we need to convert the time from minutes to hours.

There are 60 minutes in an hour, so we convert 32 minutes to hours by dividing by 60:

\[

32 \, \text{minutes} \times \frac{1 \, \text{hour}}{60 \, \text{minutes}} = \frac{32}{60} \, \text{hours} = \frac{8}{15} \, \text{hours}

\]

Now that we have the time in hours, we can calculate the average speed using the formula for speed:

\[

\text{Average Speed} = \frac{\text{Distance}}{\text{Time}}

\]

Substituting the values we have:

\[

\text{Average Speed} = \frac{4 \, \text{miles}}{\frac{8}{15} \, \text{hours}} = 4 \, \text{miles} \times \
