400/60= 6.67 Six hours and forty minutes, if you'd be able to do 60 all the time.
6 hours 40 minutes at 60 mph
Approx 4 hours 42 minutes.
about 400 miles
if there's no traffic and are on the interstates, you could actually do about 400 miles in 6 hours and not break the speed of limit of 70 miles an hour
(400 miles/trip) x (1 hour / 70 miles) = (400/70) (miles-hour / trip-miles) = 5.7143 hours = 5 hours 43 minutes, with no stops.
If you average 65 miles per hour for the entire distance your driving time would be about 6 hours and 9 minutes.
400/5 = 80 miles per hour
