Answer 1

7 miles per hour

Explanation:

Answer 2

Nia will run 6.24 miles.

Explanation:

Given:

Average speed of Nia (s) = 5.2 mph

Total time of run (t) = 1 hour 12 minutes

Distance traveled (D) = ?

First, let us convert time completely into hours.

We know that, 1 min =
`(1)/(60)\ h`

Therefore, 12 min =
`(12)/(60)= 0.2\ h`

Hence, 1 hour 12 min = 1 hour + 0.2 hour = 1.2 hours

Time (t) = 1.2 hours

Now, distance traveled is given as:

Distance = Speed × Time

`D=s* t\\\\D=(5.2\ mph)* (1.2\ h)\\\\D=6.24\ mi`

Therefore, Nia will run 6.24 miles.
