450 mph
Jet airliners travel at about 500mph
Mach 3.7
2,193.167 by the Lockhead SR-71A is the fastest for a jet plane the fastest by any plane was 4,520 by a rocket plane though
A jet plane is propelled by the force produced by its jet engines, which expel high-speed exhaust gases to create thrust. This thrust overcomes drag and allows the plane to move forward through the air.
The SR-71 Blackbird is the world's fastest jet, with an unclassified top speed in excess of mach 3. The official record was set it 1976 at 2,193 mph.
Apart from the fact that a jet plane would stall at that low a speed, the speed is equivalent to 36.657 metres per sec
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.
A plane climbs into the jet stream which is flowing at a rate of 80 miles per hour Traveling with the jet stream for 5 hours the plane covers 1150 miles The plane then reduces its altitude and flies 150.
