5 to 6 Mach... to give an example, the top speed of the 747 is only 0.9 Mach, the Concorde was 2.2 and the Boeing FA/18 Hornet is 1.8
Ramjets work with an air intake speed of, usually, 400mph+ but scramjets require supersonic air speed to function.
A Scram jet is a jet which needs supersonic propulsion to take off. It is taken into air by another larger aircraft and is released in supersonic speed.
2 mph
Current jet fighters average about 1,300 mph.
575 mph.
Average speed = Distance/Time Average speed = 5400/9 = 600 mph
The average speed of a jet plane is about 900 kilometers per hour. However, this is usually measured in knots which refers to nautical miles and this translates to about 500 knots.
The average aircraft can go 600 miles per hour.
About 16 days.
close to 600 ground MPH
About 550 Miles per hour.
The average jumbo jet (based upon a Boeing 747) can fly at a speed of 245 m/s, with its maximum speed at about 550mph. - - - - - There is no such thing as an "average jet plane." A Boeing 737 will accelerate slower than a Gulfstream V which will accelerate slower than an F-14.
