Answer:

Explanation:

In order to write an equation for the distance in miles (y) that she ran in x hours, assuming she ran at a constant rate, we can use the formula for distance:

In this case,

We need to find her rate:

Substitute the value

Now that we have her rate (R), we can write the equation for the distance she ran in x hours:

Substitute the value:

So, the equation for the distance in miles (y) that Reagen ran in x hours at a constant rate is:
