Mach 0.85 means an object is moving at 85 percent of the speed of sound in the surrounding medium. At sea level, where the speed of sound is roughly 761 mph (1,225 km/h), Mach 0...

Science and Technology

The speed of sound represents a relationship between time and distance: it is the distance sound travels in a given period. At sea level under standard conditions (around 20°C...
