The Boeing 747-300 flies at a speed of 515 Knots or 620 miles per hour. However, to assure the best lift to drag ratio, the Boeing 747-300 flies at a Mach number of .85 which is 85% of the speed of sound. The speed of sound is determined by the density of the air. Therefore, the speed of sound is less as the aircraft climbs to a higher altitude. How do I know all this. Well, I am a Boeing 747-300 Captain with Saudi Arabian Airlines.
The maximum certified operating altitude of the B747 is listed as 45,100 feet.
An A380 is a double story aircraft but the B747 is double story only in the front of the plane. A380's are alot newer the B747's.

The Boeing 777.
-- The driver of the car says that the speed of the fly is zero. -- An on-looker sitting on a park bench as the car passes him says that the speed of the fly is 80 kph. -- Both are correct, since there's no such thing as the "real speed", and speed is always referred to something.
About 8 hours. The B747-200 had a fuel capacity of 330,000 lbs and used approximately 25,000 lbs per hour. The USAF E-4 Airborne Command Post is a highly modified B747-200 that has in-flight refueling capability and extra tank for engine oil and it can fly 3 days without landing.
The minimum speed required to fly an airbus is 300 kilometres per hour.
