That depends on the type and speed of the aircraft. In an SR-71 Blackbird, it would have taken about 40 minutes. In a Piper J-3 "Cub", 1200 miles would take the better part of three days.
In an average modern airliner, it would be about 3 hours.
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.
Dividing distance travelled by speed gives 1200/250 = 4.8 hours or 4 hours 48 minutes.
It's about 1200 miles, say 2 hours and fifteen minutes, ballpark.
Depends on the speed of the plane, Planes average on about 600 mph, It would take 2 hrs for 1200 miles and for 90 miles it would take 10 mins (estimate, 100 miles would take 10 mins).So about 2hrs and 10 mins.
6,143 miles
about 4 hours
Its all on your imagination
6,313 miles
5484.510 Miles
i think its 11111 miles
It depends how quickly you travel.
