Mach is a unit of speed based on the speed of sound (which varies with altitude and pressure). Mach 1 is the speed of sound, 340.29 m/sec or about 761.2 mph at sea level. Mach 2.5 would be 2.5 times as fast, or about 1900 mph.
Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.
Yes. The space shuttle moved at a speed of 17,500 mph, which is roughly Mach 25.
Maximum speed: Mach 0.96Operating speed: Mach 0.89
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.

the Mach number
I know that in orbit, the shuttle goes about 17,500 MPH and reaches its top speed of Mach 25 upon re-entry.
The "Mach number" is the speed of the aircraft as a percentage of the speed of sound. So an aircraft going at Mach 0.74 is traveling at 74% of the speed of sound. (Mach 0.74 is a typical airliner speed.)
Mach 2.
No, Mach is a unit of speed used to measure an object's speed relative to the speed of sound in the medium through which it is traveling. For example, Mach 1 is the speed of sound.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.
