How fast in in Mach would you have to go to make it 442 miles in one minute?
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
What is mach 4 speed?
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
How many miles per hour can an A380 airbus fly?
The A380 has a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude), its maximum design speed is Mach 0.96.
How many miles per hour is mach 8?
Mach is not an absolute speed but a relative speed. The Mach value of an object is the ratio of the speed fo the object travelling through a medium to the speed of sound travelling through the same medium. Now sound travels faster in denser mediums so the speed of sound in [dense]air at sea level is greater than the speed of sound at high altitude. So Mach 2 in the air at sea level is faster than Mach 2 at high altitude. But Mach 2 under water is very much faster. However, most people are ignorant about the proper meaning of Mach and assume that it is simply related to the speed of sound at sea level at normal temperature/pressure/humidity - approximately 760 miles per hour. In that case Mach 8 would be 6080 mph.
How fast is Mach 9?
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
