Answer:
His average speed was of 10.42 m/s
Step-by-step explanation:
We use the following relation to solve this question:
[tex]v = \frac{d}{t}[/tex]
In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.
Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.
This means that [tex]d = 200, t = 19.19[/tex]
So his average speed was of:
[tex]v = \frac{d}{t} = \frac{200}{19.19} = 10.42[/tex]
His average speed was of 10.42 m/s
