How fast is Mach .88 in mph?

Answer 1

There is no finite answer to this, since the term Mach (the speed of sound through air or water) changes based on the temperature of the air itself. In 60 deg F air at sea level, Mach 1 is 761mph. In dry air at 68 deg F, mach 1 is 768 mph. Mach 1.4 is 1.4 x these speeds. Usually Mach speeds are used for objects travelling in air, but not always. Mach 1 in water is 4.3 times faster than air and Mach 1 in iron is 15 times faster than air.

Answer 2

Mach refers to a measure of speed, equivalent to the speed of sound. As such, because the speed of sound increases as the temperature increases, Mach 1 is not a constant measure. At a temperature of 15 degrees celsius, the speed of sound is equal to 340.3 metres per second. Therefore, Mach 1.6 at 15 degrees Celsius is equal to 340.3 x 1.6 = 544.48 metres per second.
