Mach 1 is the speed of sound, which varies by the air's pressure and temperature.
Mach 1 at sea level is 340.3 m/s, 764.2 mi/h, 1,225 km/h. Hope that helped!

How fast is mach 1 at 20000 feet?
2 000 000 000 feet in one second
How fast is mach 20?
Mach 20= 15,200 miles per hour.Mach numbers are determined by the speed of the object divided by the speed of sound.The speed of sound is approx. 760 miles/hour - a Mach 1 number would be the speed of the object (760 mph) divided by the speed of sound (760 mph) = 1Mach 20 would be 20 times the speed of sound (760 mph) = 15,200 mph.It is absurd to think that the government just lost an aircraft flying at the speed of 700 billion mph!
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.
How fast is 1 knot in miles?

How do you measure velocity in supersonic jet?
-- Measure the distance between two points.-- Measure the time it takes the jet to fly from one point to the other one.-- The speed of the jet between the two points is(the distance between them)/(the time it takes to fly from one to the other)
How fast is mach 20 in mph?
Mach 1 is about 762 mph, so mach 20 is about 15,240mph.
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.
Are 1971 mustang fastback and 1971 mach 1 the same car?
no that's why ones called a fast back and the other ons a mach 1
What do you mean when you say that the Concorde can travel at mach 2?
mach 1 = the speed of sound mach 2 is twice the speed of sound and that's how fast Concorde could travel, well, mach 2.3
