It all depends on the jet. The F111 for example, a classic military bomber, could fly for a few minutes over mach with AB, but eventually it had to slow down b/c the airframe overheated due to friction. Private jets have a top speed based on airframe stresses, and they can fly all day at or below this speed in calm air. Their engines have a take off only setting, which wouldn't damage the turbine to use for long times, but its life would be dramatically depressed.
A typical Jumbo Jet will fly at 550-600 mph top speed.
It depends on the model of the Royal Air Force fighting jet that you are asking about. But the Eurofighter Typhoon jet, has a top speed of 1,320mph.
The top speed of an A-10 is 440 mph.
It is 1,550mph
Its top speed is more than 1600mph(mach2.4).
165 mph
Gazelles run about 48 KM/H, which would be about 30 MPH.
depends on the jet, a Boeing 747-400 has a top speed of 614 mph at 35,000 feet
Approximately 1,500 mph .
About 2500 km per hour.
With the SR-71 Blackbird being the fastest jet and having a top speed of 4100 mph, it would take roughly 6.073527548005815 hours.
It depends what plane but it can reach approximately 900 KM/H
