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

The displacement of the beetle is

The time is t=12.8 s
Therefore, the average velocity is

in the positive x-direction.
In that case, it will change it's identity to the atom of one degree less than that!
Hope this helps!
