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 3 would be approx 2280 mph. But Mach 3 in water, for example, would be much faster since sound travels faster in water.

distance = velocity X time 1km = 20 kph X time time = 1 km/(20 kph) = 1/20 of an hour or 3 min.

Mach I (the Speed of Sound) is approximately 1,236 km/h (738 mp/h). This is dependent on the air pressure. At sea level, the speed of sound is about 760 mph; at high altitude it reduces closer to 600 mph.

A Stinger missile has a speed of around Mach 2.2, which is roughly 2,685 km/h or 1,670 mph.

The crusing speed of the concord jet is Mach 2, or 1,336 mph (2,150 kph).

Mach 3 = 2283.6211 mph

For an Exotic read "The AURORA Program" sees the stealth aircraft evidence supporting Mach 8 and beyond. It would depend on the jet itself. Each jet has a different engine (thrust production), weight, lift and drag component which all effect the top speed of fighter jets. For example the f18 hornet has a top speed of mach 1.8 (1190 kph) whilst the yet the mig 35 can get to mach 2.25(2400 kph)

500 mph = 804.7 kph

The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.

Mach 3 is 2283.6211 mph because Mach 1 equals 761.207033 mph.
