Mach velocities are all relative to the speed of sound in that gas, at that density.
Mach 1 = the speed of sound. Mach 2 = twice the speed of sound.
It does not have an invariant conversion into miles per minute.
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
Mach 2.2 refers to 2.2 times the speed of sound. The speed of sound is variable, depending on pressure and temperature. The speed of sound on a standard day at sea level is approximately 762 miles per hour. Mach 2.2 on a standard day at sea level would be approximately 1676.4 miles per hour, or 27.94 miles per minute, or approximately half a mile per second.
You would have to maintain a pace of at least 5.63 miles per hour.

Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
Mach 19 is 14,462,934 miles per an hour
Mach 10 = 7,612.1 mph
Mach 6 is about 4,567 mph
Mach 2.2 refers to 2.2 times the speed of sound. The speed of sound is variable, depending on pressure and temperature.

How fast is 0.85 mach?
1,150.9 miles per hour.
The SR-71 Blackbird is 2,193 miles per hour fast or Mach 3, three times faster than the speed of sound.
Mach 10 = about 7,606 miles per hour.
Mach one is the speed of sound, which is about 761.2 miles per hour (340.3 meters per second). Mach two is twice the speed of sound, which is about 1,522.4 miles per hour (680.6 meters per second).
It would be an approximate 2,380.8mph.
