The maximum speed of a 747 is Mach 0.92.
The maximum speed is 0.92 mach.
The 747-400, which is the most common variant in service, has a high-subsonic cruise speed of Mach 0.85-0.855 = up to 570 mph or 920 km/h
585 mph cruising speed
The lift off speed is dependant upon the weight of the aircraft. The heavier the aircraft the higher the speed. At maximum take off weight of 875,000 lbs (396,890 kgs) Vr (rotation speed) will be about 175 knots and V2 about 185 knots.

maximum speed is 0.92 mach.
Max speed is 0.92 mach.
In cruise flight the normal speed is 0.85 mach. Maximum speed is 0.92 mach
Cruising speed is around 570 mph. Maximum speed is around 614 mph.
Cruising speed is 585 mph. The max speed for a 747-8 is 614mph, or 988km/h.Maximum speed = 0.92 machI recently watched a YouTubevideo of a Boeing 747 that reached a ground speed of 744 MPH (1196 km/hr). This is the highest speed that I know of that a 747 has ever flew. Here's the link to the video if you want to watch it. http://www.youtube.comwatch?v=AHrsYKTnGAUIt's titled "Boeing 747 Fastest Speed Commercial Flight".0.85 Mach567 mph (913 km/h)AnswerThe Boeing 747 cruises at around 0.85 Mach, but in answer to how fast "can" one go, the answer is that Vmo/Mmo (maximum operating speed/mach) for the earlier versions is 0.89 Mach and for the 747-400 it's 0.92 Mach.
The 747-400, which is the most common variant in service, has a high-subsonic cruise speed of Mach 0.85-0.855 = up to 570 mph or 920 km/h
The Boeing 747-8I series has a cruising speed of 570 mph (Mach 0.855). It's maximum speed (both the 400 and 8I series) is 614 mph (Mach 0.92).
With zero wind and depending on the model the average 747 will cruise at .82 mach. The ground speed will increase proportionally with the tail wind.
Maximum speed for a 747 is 0.92 mach. Normal cruise is between 0.82 and 0.85 mach at altitudes up to 45,100 feet. meaning about 200 mph give or take.
