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
Mach 24 is roughly equal 18,264 miles per hour. Mach is a term used to describe the ration of the speed of an object to the speed of sound. The speed of sound, at sea level, is roughly 761 mph. Mach 24 means that the ration of the speed of an object to the speed of sound is 24, meaning 24 times the speed of sound. Thus, at sea level, an object travelling at mach 24 is travelling at 24 times 761mph, which is 18,264 miles per hour.
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.
Maximum speed for a 747 is 0.92 mach. Normal cruise is between 0.82 and 0.85 mach at altitudes up to 45,100 feet. meaning about 200 mph give or take.
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.
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.
0,72 Mach is a subsonic speed. Mach number = speed of an object/speed of sound The speed of sound in dry air at 20 0C is 1 236 km/h.
