1 hour and 14 minutes
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.
184 miles.
One hour.
t = d/|v| = 400 mi / (80 mi / h) = 5 h
Exactly 100 miles
It would take 1 hour 19 minutes and 38 seconds to drive 73 miles at 55 miles an hour.
"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.
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.
That depends how fast you drive, if your average speed was 28 miles per hour it would take one hour, if your average speed doubled to 56 miles per hour it would take just half an hour.
