If you could drive non-stop at a constant speed of 80 mph, it would take about 7 hours and 30 minutes.
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.
1 hr = 60 mins time = distance ÷ speed = 8 miles ÷ 80 miles/hour = 0.1 hour = 0.1 x 60 mins = 6 mins.
Exactly 100 miles
It would take 1 hour 19 minutes and 38 seconds to drive 73 miles at 55 miles an hour.
If you drove at 38 mph then it would take you one hour to drive 38 miles. If you drove at 76 mph it would take you half an hour to drive 38 miles
Answer 7.5 miles an hour should do it. 7.5 miles an hour
At 60 miles an hour, 4. At forty miles an hour, 6.
t = d/|v| = 400 mi / (80 mi / h) = 5 h
"80 miles per hour" means "at the speed of 80 miles in one hour" so it would take one hour to drive 80 miles at 80 miles per hour.
