Question

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

Answer 1

Answer:

20m/s

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  = $\frac{displacement}{time}$  

So;

   Velocity   = $\frac{200}{10}$   = 20m/s
