The Mach number is a measure of the ratio of the speed of an object to the speed of sound in the medium through which the object is traveling. It is used to describe how fast an object is moving compared to the speed of sound. For example, Mach 1 is the speed of sound, so a Mach number greater than 1 indicates supersonic speeds.
the Mach number
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.
889 mach is approximately 683,781.4 mph.
Mach 1 (or the speed of sound) is 1,225km per hour Mach 75 is there for 91,875 km/h
Mach 0.6 is equal to 460.68 miles per hour.
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.
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
Maximum speed: Mach 0.96Operating speed: Mach 0.89

To mach for you if you cant spell it.

Ernst Mach .
Mach 1 is about 762 mph, so mach 20 is about 15,240mph.
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.
