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.
12000 hours at mile/hour
Dividing distance travelled by speed gives 1200/250 = 4.8 hours or 4 hours 48 minutes.
Its all on your imagination
6,143 miles
about 4 hours
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.
It depends how quickly you travel.

6,313 miles
5484.510 Miles
i think its 11111 miles
10 minutes for every 100 miles
