Question

Ariel travels 400 miles in 8hr. What is her of change or speed?

Answer 1

We need to find the rate of change when Ariel travels 400 miles in 8 hours.

Now, the rate is given by the next formula:

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

Replacing using the given values:

Distance = 400 miles

Time = 8 hours

Then:

`\begin{gathered} \text{Rate}=\frac{400\text{ miles}}{8\text{ hours}} \\ \text{Rate}=50\text{ miles/hours} \end{gathered}`

Hence, the answer is 50 miles per hour.
