Question

a que velocidad en km/h corrio usain bolt en el capeonato mundial de berlin en 2009 para batir el record mundial de los 100 m planos en 9.58

Answer 1

v = 37.59 km/h

Step-by-step explanation:

The question says, "how fast in km / h did usain bolt run at the berlin world championship in 2009 to break the world record for the 100m sprint in 9.58".

Distance, d = 100 m = 0.1 km

Time, t = 9.58 s = 0.00266 h

We need to find the speed of the Usain Bolt. We know that,

Speed = distance/time

So,

`v=(0.1)/(0.00266)\\\\v=37.59\ km/h`

So, the required speed is equal to 37.59 km/h.
