The answer is in the "Miles per hour" (Mph) you drove. If you drove 40 Mph, then in one hour you would have driven 40 miles. Therefore, in five hours, at the constant speed of 40 Mph, you would have drive 200 miles.
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.

21 hours.
At 60 miles per hour it would take about 4 hours.
At 60 miles an hour, 4. At forty miles an hour, 6.
It would take 1 hour 19 minutes and 38 seconds to drive 73 miles at 55 miles an hour.
