What is Mach number?
In the case of an object moving through a fluid, such as an aircraft in flight, the Mach number is equal to the velocity of the object relative to the fluid divided by the velocity of sound in that fluid. Mach numbers less than one indicate subsonic flow; those greater than one, supersonic flow.

What is Mach number in speed?
What is Mach? The Mach number describes the aircraft's speed compared with the speed of sound in air, with Mach 1 equating to the speed of sound.

The Mach number is primarily used to determine the approximation with which a flow can be treated as an incompressible flow. The medium can be a gas or a liquid.

Sure, there are hypersonic weapons, most of them in testing stages, but to date not a single human was capable of reaching Mach 10 in an aircraft while inside the atmosphere. The closest someone (Capt. Eldon W. Joersz and Maj

How fast is a Mach 10 in mph?
7000 mph
As the final X43A flew, blistering temperatures created by the nearly Mach 10 (7000 mph) speed were in the neighborhood of 3600 degrees, the hotspot this time being the nose of the vehicle.

The NASA/USAF X15 is the fastest fighter jet ever produced. It reached record top speed of Mach 6.72 or 4,520 mph, which is more than five times the speed of sound.

Whats the fastest jet?
Lockheed SR71 Blackbird
The Lockheed SR71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3that's more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR71's design made this possible.

How many mph is supersonic?
768 miles per hour
How Fast Is Supersonic Speed? The exact definition of supersonic speed changes based on altitude, temperature, and atmospheric conditions. A measure of 768 miles per hour is given as a “standard” supersonic speed when traveling in dry air at sea level at 68°F
