Mach is the speed of an object expressed as a multiple of the speed of sound in the same medium. Thus, an object travelling at 686 metres per second through air, at sea level, is travelling at Mach 2 because sound would travel through it at 343 m/s. However, it the object was travelling under water at the same speed then it would be travelling at approx Mach 0.46 since sound travels at 1484 m/s through water.

How fast is mach1?
Mach 1 is one times the speed of sound, which equals the speed of sound, which is 768mph.
What speed is mach 9?
Mach 9 = 3,062.61 m/s = 11,025.396 km/hrMach 9 is 9 times the speed of sound.
What is mach regarding speed?
That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
How fast is a mach 10?
That means 10 times the speed of sound.That means 10 times the speed of sound.That means 10 times the speed of sound.That means 10 times the speed of sound.
What speed is 0.72 Mach?
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.
How fast is Mach 1 Mach 2 Mach 3 Mach 4 etc to the fastest Mach level on record?
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.
What does Mach 25 mean?
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.
Why is Mach times the speed of sound?
That's how "Mach" is defined.
What is 96mach?
0.96 mach is 96% the speed of sound. Mach 96 would be 96 times the speed of sound.
What is mach 8?
It means 8 times the speed of sound. Something travelling at 8 times the local speed of sound is said to be traveling at mach 8
What is the word 5 times the speed of sound?
Mach 5.
How fast is mach1?
Mach 1 is one times the speed of sound, which equals the speed of sound, which is 768mph.
What speed is Mach 2.5?
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.
What does Mach 3.2 mean?
It means 3.2 times the speed of sound.
How many miles per hour can supersonic fly?
Mach refers to the speed of sound in air. Typically about 750 mi/hr but it varies faster or slower with temperature from cold to hot respectively. Mach one is one times speed of sound. Mach 3 would be three times speed of sound.
How fast is Mach 2.4 in mph?
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.
What speed is mach 9?
Mach 9 = 3,062.61 m/s = 11,025.396 km/hrMach 9 is 9 times the speed of sound.
