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!
