It would take 7 hours.

If you are going at 45 miles per hour, you need to find out how much 45 goes into 315.

To deduce this, divide 315 by 45.

315/45=7

It would take 7 hours.

Hope this helps!

Answer:

7 hours

Step-by-step explanation:

Write it out like a ratio X/315 = 1/45

Let X be hours

Cross multiply 315 x 1

and 45 x X -------> this gives you 315 = 45X

Then simply divide both sides by 45 and you get 7 hours
