<span>Distance covered by Mario in 6 hours is 330 miles.
Then, Average speed of Mario is 330 miles divided by 6 hours = 55 miles per hour
so to drive a total distance of 715 miles, it would take him ( 715 miles divided by 55 miles per hour) hours

so Mario will have to drive for 7 more hours to complete a total distance of 715 miles.</span>
