A beetle crawls from x=1.09m to x=2.55m in 12.8s. what was the average velocity?
Ivan

The average velocity of the beetle is equal to the ratio between the displacement and the time:

v=\frac{S}{t}


The displacement of the beetle is

S=2.55 m-1.09 m=1.46 m

The time is t=12.8 s


Therefore, the average velocity is

v=\frac{S}{t}=\frac{1.46 m}{12.8 s}=0.11 m/s

in the positive x-direction.
