Question

Joy ran 13 miles in 3 and 1/4 hours. What was her average rate?

Answer 1

Answer: 4 miles per hour.

Explanation:

Total distance ran by Joy= 13 miles

Total time taken by Joy =3 and 1/4 hours

`=3+(1)/(4)\ hours\\=(13)/(4)\ hours`

The average rate of running=
`\frac{\text{total distance}}{\text{time taken}}`

`(13)/((13)/(4))=(4)/(1)=4\text{ miles per hour}`

Hence, her average rate=4 miles per hour.
