The way this is worded is tricky so I'm going to give you the answer to the question I think you meant to ask. The average speed of a large commercial jet airliner is about 500 mph. A "passenger plane" can be anything from an ultralight on up. If you go from ultralights to jets and everything in between that has more than one seat, your average speed drops drastically.
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
800mph
165 mph
Its top speed is more than 1600mph(mach2.4).
depends on the jet, a Boeing 747-400 has a top speed of 614 mph at 35,000 feet
About 2500 km per hour.
Approximately 1,500 mph .
I know below 10000 feet is 250 knots.
It depends what plane but it can reach approximately 900 KM/H
