The speed can be calculated using the formula below:
[tex]speed=\frac{dis\tan ce}{\text{time}}[/tex]In this question:
Distance = 80 meters (distance of the park).
Time = 16 secons.
Substituting the values:
[tex]\begin{gathered} speed=\frac{80}{16} \\ speed=5\text{ m/s} \end{gathered}[/tex]Answer: The speed of Anne is 5 m/s.
