7 hours 26 minutes (approx).
The time it takes to drive 20 miles depends on the speed at which you are driving. If you are driving at a constant speed of 40 miles per hour, it would take you 0.5 hours to drive 20 miles (20 miles / 40 miles per hour = 0.5 hours). If you are driving at a constant speed of 60 miles per hour, it would take you 0.33 hours to drive 20 miles (20 miles / 60 miles per hour = 0.33 hours).
175 miles at 65 miles per hour would be 2.69 hours
Divide 249 miles by 70 Miles/hour to get 3.557142857 hours.
That depends on the speed at which you are driving. For example, if you are driving 52.6 miles/hour, it would take an hour to drive that far. If you are driving 23.8 miles/hour, it would take two hours to drive that far.
