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.

How fast is 2000 kilometres per hour?
1,242.7 miles per hour.
How many kilometres per hour does 0.82 mach equal?
1225 x 0.82 = 1004.5 Km/h
How fast is 35mph in kilometers per hour?
There are 1.609344 kilometres in one mile. Therefore, 35 miles per hour is equal to 35 x 1.609344 = 56.32704 kilometres per hour.
How fast is Mach 9?
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
How fast 23 knots in miles per hour?
1 knot is defined as exactly 1.852 kilometres per hour. Therefore, 23 knots is equal to 23 x 1.852 = 42.596 kilometres per hour.Converted to miles per hour, and rounded to two decimal places, 42.596 kilometres per hour is equal to 26.47 mlies per hour.
