41 miles per hour.

Explanation:

We have been given that the Martinez family drove 48.7 miles to the river. It took them 1.2 hours to get there. We are asked to find their rate.

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

`\text{Speed}=\frac{\text{48.7 miles}}{\text{1.2 hours}}`

`\text{Speed}=\frac{\text{40.58333 miles}}{\text{ hour}}`

`\text{Speed}\approx \frac{\text{41 miles}}{\text{ hour}}`

Therefore, the Martinez family are driving at a rate of 41 miles per hour.
