Answer:
[tex]v=2.2m/s[/tex]
Explanation:
Hello.
In this case, since the velocity is computed by the division of the distance traveled by the elapsed time:
[tex]v=\frac{d}{t}[/tex]
Thus for the 140 m that were walked in 65 seconds, the velocity turns out:
[tex]v=\frac{140m}{65s}\\ \\v=2.2m/s[/tex]
Best regards.
