Best Answer

The Mach number for the speed of an object travelling through a particular medium is the ratio of the object's speed relative to the speed of sound through the same medium. The speed of sound through any medium depends on the nature and density of the medium and, as a result, so does the Mach number. In air, the Mach ratio is mostly dependent on temperature and humidity, less so on altitude.

Generally, Mach 1 (in air, at standard sea level conditions, and at 15 deg C) is approx 760 mph. So Mach 1.8 would be approx 1370 mph.

Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.

Rounded to two decimal places, Mach 1 is equal to 761.21 miles per hour. Multiplying this by 1.6 gives us 1217.38 miles per hour.Converting 1217.38 miles per hour to metres per second gives us 544.46 metres per second.

Mach 10 = 7,612.07 mph

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.

It is81.25 miles per hour
