The speed of sound has nothing to do with jet airplanes. About 750 mph, and it was that before jets, and even the Acropolis were built.
Speed of Sound = 343.14 m/s 4 miles = 6437 metres 6437/343.14 = 18.76 seconds
Chuck Yeager, a United States Air Force officer, was the first American pilot to exceed the speed of sound in an airplane during a test flight in 1947. This achievement was a significant milestone in aviation history and marked the beginning of supersonic flight.
Bell X-1 named, "Glamorous Glennis".
The average speed if an airplane travels 1364 miles in 5.5 hours is 248 miles/hr.
The passenger airplane that flies faster than the speed of sound is called the Concorde.
Supersonic.
It is going faster than the speed of sound.
Air speed or ground speed?
153 mph
When an airplane travels faster than the speed of sound, it creates a sonic boom. This is a loud noise produced by the shock waves formed as the aircraft exceeds the speed of sound.
The speed of sound does not travel. In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster than the speed of the airplane. On the occasion and at the moment when the true indicated airspeed of an airship or an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the speed of sound.
7.5 miles per hour
