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.
5 hours 20 minutes. This is the total driving time at that speed and excludes stops or delays.
400 km per hour is 248.55 miles per hour.
There are 5280 feet in one mile. Therefore, 400 miles per hour is equal to 400 x 5280 = 2112000 feet per hour.
400/5 = 80 miles per 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.
It will take: 5 hours and 20 minutes
5hours 42minutes 51.43seconds (rounded)
8 hours and 53 minutes
It takes 22 minutes 12 seconds to fly 148 miles at 400 miles per hour.

t = d/|v| = 400 mi / (80 mi / h) = 5 h
5 hours 20 minutes at a constant 75 mph, excluding stops.
The speed appears to be 400 miles an hour. If you meant 400 miles, the speed is 50 miles an hour.
