Question: The average velocity of a particle moving in one dimension has a positive value. Is it possible for the instantaneous velocity to have been negative

The average velocity of a particle moving in one dimension has a positive value. Is it possible for the instantaneous velocity to have been negative at any time in the interval? Suppose the particle started at the origin x ! 0. If its average velocity is positive, could the particle ever have been in the #x region of the axis?
