400/5 = 80 miles per hour
5 hours 20 minutes.

400/60= 6.67 Six hours and forty minutes, if you'd be able to do 60 all the time.
400/5 = 80. HBD!
To calculate the flight time for 1200 miles at a speed of 400 mph, divide the distance by the speed: 1200 miles ÷ 400 mph = 3 hours. Therefore, it will take 3 hours to fly 1200 miles at that speed.
5 hours 20 minutes.
(400 miles/trip) x (1 hour / 70 miles) = (400/70) (miles-hour / trip-miles) = 5.7143 hours = 5 hours 43 minutes, with no stops.
Speeding.
The speed appears to be 400 miles an hour. If you meant 400 miles, the speed is 50 miles an hour.

400 mph means it travels 400 miles in ONE hour. So it travels 4000 miles in ten hours. And 8000 miles in 20 hours.6000 is half way between 4000 and 8000, so 15 hours is half way between 10 and 20.Or you can just divide 6000 by 400.
400 / 13 = 30 hours and 48 minutes
The speed of the jet stream is 110 mph (550 miles / 5 hours). In 5 hours, the plane covers 400 miles (80 mph x 5 hours). In 4 hours, the plane covers 320 miles (80 mph x 4 hours), but it actually covers 550 miles less due to the effect of the jet stream. So, the total distance traveled by the plane in 9 hours would be 720 miles (400 miles + 320 miles).
