400/60= 6.67 Six hours and forty minutes, if you'd be able to do 60 all the time.
400/5 = 80 miles per hour
400/5 = 80. HBD!
Answer: 400 km/h = 248.548 mph
60 minutes = 1 hour so 400 min = 400/60 = 6.66... hours. Simple!
The time it takes to travel 400 miles depends on the average speed. If the average speed is 50 miles per hour, you will travel 50 miles in the first hour, 50 more in the next, 50 more in the next and so on. The number of hours it will take is equal to the number of 50 mile stretches in 400 miles. That's 400 divided by 50, which is 8. It will take 8 hours to travel 400 miles at an average speed of 50 miles per hour. In general, if your average speed is s, then it will take 400 divided by s, or 400/s hours. Whatever the distance is, let's call it d, the time taken to travel is is d/s. It depends on the mode of transportation and the speed in which it is moving at.
8 hours
The speed appears to be 400 miles an hour. If you meant 400 miles, the speed is 50 miles an hour.
8 hours
(400 miles/trip) x (1 hour / 70 miles) = (400/70) (miles-hour / trip-miles) = 5.7143 hours = 5 hours 43 minutes, with no stops.
Approx 4 hours 42 minutes.
400/5 = 80 miles per hour
If you average 65 miles per hour for the entire distance your driving time would be about 6 hours and 9 minutes.
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
A little more than 5.
