* Mach number represents the ratio of an object's speed to the speed of sound.
* The speed of sound varies slightly depending on temperature and altitude, but we'll use the standard value of 767 mph (1235 km/h) at sea level and room temperature.
Calculation:
* Mach .88 means the object is traveling at 0.88 times the speed of sound.
* Speed in mph = Mach number * Speed of sound
* Speed in mph = 0.88 * 767 mph
* Speed in mph = 675.56 mph
Therefore, Mach .88 is approximately 675.56 mph.
