Question

What is the velocity of a Usain Bolt if he runs 200 m in 10 seconds?

Answer 1

20m/s

Step-by-step explanation:

Given parameters:

Displacement = 200m

Time = 10s

Unknown:

Velocity of Usain Bolt = ?

Solution:

The velocity of a body is the displacement divided by the time taken.

Therefore

Velocity =
`(displacement)/(time)`

So;

Velocity =
`(200)/(10)` = 20m/s
