567 mph
The cruising altitude of Boeing 747 is 30,000 feet.
A 747 typically cruises at 0.84 mach/560 nautical miles per hour.
Cruising speed is around 570 mph. Maximum speed is around 614 mph.
A Boeing 747 typically cruises at a speed of around 550-600 miles per hour (880-960 kilometers per hour).
The Boeing 747 typically has a maximum cruising speed of around 570 miles per hour (917 kilometers per hour) at altitude. However, the exact speed can vary slightly depending on the specific model of the 747, such as the 747-400 or the 747-8. In general, this iconic aircraft is designed for efficient long-distance travel rather than high-speed performance.
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.
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).
If you are talking plane or car, car is the SSC THRUST. No plane has gone that speed at ground level, so i wouldn't know.
The cruising altitude of a 747 depends on weather conditions, weight of the aircraft, and the amount of traffic on the other flight levels. Its average cruising altitude is around 33,000 feet.
An aircraft waiting to land is not cruising, it either on final approach so defending and slowing to 140 knots or is held in pattern at a speed dictated by act normally 180 to 200 knots
