That very much depends on the type of airplane. In a WW1 biplane, it could be 5 or 6 hours. In a Boeing 737-800, less than an hour.
At 500 mph, it would take an airplane 4 hours to fly 2000 miles.
About 43 minutes.
The Cessna Citation X could do that in about 1 hour. It would take the Cessna 152 about 5 hours
That would depend on how fast the airplane is flying. If the plane is flying 425 miles per hour it would take 1 hour. At 212.5 miles per hour it would take 2 hours.
26 years.
24,901 miles at 500 mph would require 2.08 days.
2.5hrs
The distance to cover is around 900 Nautical Miles. A jet airplane would take about 2.5 hours to fly this.
It would take an infinite amount of time because the airplane could not get to the moon, at all. An airplane can only get to a small distance above the earth's surface.
What kind of Airplane? If a jet, most likely take anywhere from 7-9 hours.
That takes 8 hours.
The time will vary widely depending on the type of airplane. At 351.5 miles per hour, it will take one hour.
