Mach is the coefficient of the speed of sound, so Mach 1 means you are travelling at 1 x the speed of sound.
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.
1 x 670, 2 x 335, 5 x 134, 10 x 67 = 670
1.4758
Mach 1 is about 762 mph, so mach 20 is about 15,240mph.

100,000 cm = 1 km so 670 cm = 670/100,000 = 0.0067 km. Simple!
