Answer 2

`10.7933\ \text{m/s}`

Explanation:

d = Distance traveled by sprinter = 200 m

t = Time the sprinter ran for = 18.53 seconds

Average speed is given by

`s=(d)/(t)`

`\Rightarrow s=(200)/(18.53)`

`\Rightarrow s=10.793308\approx 10.7933\ \text{m/s}`

The average speed of the sprinter rounded to 4 decimal places is
`10.7933\ \text{m/s}`.
