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`

Step-by-step 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}* \text{time}`

Insert the values

`\Rightarrow 200=v* 19.19\\\\\Rightarrow v=(200)/(19.19)\\\\\Rightarrow v=10.42\ m/s`

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