What is the cruising speed of the Boeing 747?

The cruising speed of the Boeing 747 is approximately 500 knots. This speed is optimal for long-distance flights, allowing the aircraft to balance efficiency and performance during cruise phases of flight. When designing and operating an aircraft, manufacturers strive to achieve speeds that ensure safety, fuel efficiency, and passenger comfort. For the Boeing 747, the cruising speed of around 500 knots reflects its design as a long-haul commercial aircraft capable of carrying large numbers of passengers and cargo over vast distances.

Other choices represent speeds that are not typical for a Boeing 747 during cruise, as they either exceed the operational limits or do not align with the performance metrics established for this model.
