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) = 1
Mach 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!

How fast is Mach 1?
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! -Jeffrey
How fast is mach 1 at 20000 feet?
2 000 000 000 feet in one second
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.
What is the decolorizing agent in the acid fast stain?
The decolorizing agent in the acid fast stain is acid alcohol. The decolorizing agent in the gram stain is ethanol.
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 20 is 20 times the speed of sound, which is approximately 767 mph at sea level and room temperature. Therefore, Mach 20 would be 20 x 767 mph, which equals 15,340 mph. This speed is extremely fast and is typically associated with hypersonic flight and reentry vehicles.
