Answer:
[tex]t=18.18s[/tex]
Explanation:
From the exercise we know that the person change its initial velocity from 5m/s to 11 m/s for 200m
According to the formula:
[tex]v=\frac{x}{t}[/tex]
If we want to know how much time does it take to cover 200 m at 11 m/s we need to calculate the following formula:
[tex]t=\frac{x}{v}=\frac{200m}{11m/s}=18.18s[/tex]
