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!

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!
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.
1 knot=1.15077945 miles per hour
-- 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)
Mach 1 is about 762 mph, so mach 20 is about 15,240mph.
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.
no that's why ones called a fast back and the other ons a mach 1
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
about 1.7 mach without afterburners with afterburners 1,317 mph over 2 mach (1 mach speed of sound about 680 mph
