How fast is Mach 5 in kilometres per hour?
about 2.5 mph 2.5 mph would be the correct answer had you asked how fast 5 KPH is in MPH, but that's not what you asked. While "mach" changes based on conditions of temperature, pressure, and elevation it's essentially the speed of sound. Roughly 340 m/sec. Doing the math from there, 340 * 5 = 1700 m/sec or 1.7 km/sec. Multiply by 60 for seconds and again by 60 for minutes and you get 1.7 km/sec * 60 seconds in a minute * 60 minutes in an hour = 6120 KMH.
