Answer:

His average speed was of 10.42 m/s

Step-by-step explanation:

We use the following relation to solve this question:

$v = \frac{d}{t}$

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 $d = 200, t = 19.19$

So his average speed was of:

$v = \frac{d}{t} = \frac{200}{19.19} = 10.42$

His average speed was of 10.42 m/s

$1\dfrac{2}{3}-\dfrac{11}{15}=1\dfrac{2\cdot5}{3\cdot5}-\dfrac{11}{15}=1\dfrac{10}{15}-\dfrac{11}{15}=\dfrac{25}{15}-\dfrac{11}{15}=\dfrac{14}{15}$
