How many km per hour can a human run?

Answer 1

Minimum 10 kilometers per hour for an average adult. This is applicable ONLY for those who are fit.

The fastest a man has run in Track and Field competition is when Michael Johnson ran the 200 meters in 19.32 seconds. That breaks down to an average speed of 23.157 MPH or 36.268 kmH.
The new fastest man is now Usain Bolt of Jamaica who ran the 200 meters in the 2008 Olympics in 19.30 breaking Michael Johnson world record and his average speed was 37.3057 kph = 23.1806873 mph

Answer 2

100 metres in 9.58 seconds equates to 0.1 kilometres in 0.0026611 hours, which gives a speed of 37.578 kilometres per hour. As this is the average speed over the distance and much of this is spent accelerating, the speed for that portion would be much lower than this. The peak speed could thus be easily above 40 kmh-1.

Answer 3

Human can run 64.3kmph (40mph). This is a human's top speed.

Answer 4

30km/h
