The average velocity of the beetle is equal to the ratio between the displacement and the time:
[tex] v=\frac{S}{t} [/tex]
The displacement of the beetle is
[tex] S=2.55 m-1.09 m=1.46 m [/tex]
The time is t=12.8 s
Therefore, the average velocity is
[tex] v=\frac{S}{t}=\frac{1.46 m}{12.8 s}=0.11 m/s [/tex]
in the positive x-direction.
