    Answer: 441 miles.

    Explanation:

    First, we have to try to find how many miles he can drive in 1 hour. To do this, we need to divide 315 by 5. This will give us 63. So now we know that 63 miles = 1 hour.

    Next, now that we know the how many miles he drives in an hour, we use 63 in this equation: 7 (miles in an hour). If we transfer all of the values into the equation, the equation will be: 7 (63) or 7 x 63.

    Then, now we know the equation we need to solve the problem. We have to solve it. So 7 x 63 is 441 miles.

    Finally, we solved the problem!

    441 miles

    Step-by-step explanation:

    First, find the constant rate of change.

    You would do 315/5=63

    63 is the constant rate of change

    Then, you would multiply.

    63x7=441
