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.

Divide the distance by the speed.

60 mph

An average speed of 40 miles per hour.

Depends on the average speed travelled. At 56 miles per hour average it will take 1 hour. The distance needs to be divided by the average speed to obtain the answer.
