The average speed of a 747 is about 560 mph.
The average speed of a passenger plane during flight is around 500 to 600 miles per hour.
In cruise flight the normal speed is 0.85 mach. Maximum speed is 0.92 mach
At the moment it is the Boeing 747-473 (747-400) operated by Air India. However, Air India placed orders for more than 50 aircraft in 2006 (most have been delivered) including the Boeing 787. The Boeing 787 Dreamliner, when it arrives in Air India in late December 2011, will be the fastest passenger plane in India.
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.
The average cruising speed of a Boeing 707 passenger plane is about 600 miles per hour. For a 500-mile flight, if we assume the flight operates at this cruising speed without significant delays or changes in speed, the flight would take approximately 50 minutes. However, actual flight times may vary due to factors like takeoff, landing, and air traffic control.
Most Boeing passenger liners would land around 130 mph.

The speediest plane I have ever witnessed was the Boeing X-51 WaveRider which can run at up to Mach 5, which is 5 times the speed of sound.
The normal cruising speed of a passenger plane typically ranges from 500 to 600 miles per hour (approximately 800 to 965 kilometers per hour). This speed can vary depending on the aircraft type and altitude. For example, most commercial jets like the Boeing 737 or Airbus A320 usually cruise at around 550 mph (885 km/h). Factors such as weather conditions and air traffic can also influence a plane's speed during flight.
A Boeing 777 has a take off speed of about 165 to 215 miles per hour. A typical Boeing 777 can carry 314 to 451 passengers and is a long-range wide-body plane.
