5 hours at a constant 70 mph, excluding speed changes, delays or stops.
Five hours.
It would take five hours.
It depends on the speed at which you drive. If you drive at a constant rate of 70 mph, you can drive 350 miles in 5 hours.
Distance = Speed*Time = 70*5 = 350 miles.
The question is unanswerable unless we know what speed you are moving (driving).If you are moving at 50 miles per hour, it will take 7 hours. If 70 mph, it will take 5 hours.If 350 mph, just one hour.
350 miles divided by 5 hours is 70 miles per hour. 350 mi / 5hr = 70 mi/hr
350 mph = 0.098 miles per second.
Traveling 261 miles at 70 mph takes 3.73 hours.
18.5 hours @70 mph
70 minutes = 70/60 hr = 7/6 of an hour. So Miles/hour = (4 miles)/(7/6 hour) = 24/7 MPH which is about 3.43 MPH.
70 miles = 112.65 km so 70 mph = 112.65 kph
