The average speed of the sprinter in kilometers per hour is about 35.0 km/h
<h3>Further explanation</h3>
Acceleration is rate of change of velocity.


<em>a = acceleration ( m/s² )</em>
<em>v = final velocity ( m/s )</em>
<em>u = initial velocity ( m/s )</em>
<em>t = time taken ( s )</em>
<em>d = distance ( m )</em>
Let us now tackle the problem !
This problem is about Kinematics.
We will solve it in the following way
<u>Given:</u>
distance traveled = d = 200.0 m
time taken = t = 20.6 s
<u>Unknown:</u>
average speed = v = ?
<u>Solution:</u>



Next we will change the units of this speed into km/h.
