Question

Usain bolt ran the 200m race within 19.19 seconds. Calculate the speed of Usain bolt during the race

Answer 1

Answer: $10.42\ m/s$

Explanation:

Given

Usain Bolt ran the race with a length $200\ m$

Time is taken to complete it $t=19.19\ s$

We know, $\text{Distance}=\text{speed}\times \text{time}$

Insert the values

$\Rightarrow 200=v\times 19.19\\\\\Rightarrow v=\dfrac{200}{19.19}\\\\\Rightarrow v=10.42\ m/s$

So, the speed of Usain Bolt is $10.42\ m/s$
