A person is born on point A and dies on point B, point A = point B. What is her/his average velocity?
I know that the answer should be 0, but is there any possibility for the person’s average velocity to be any number that isn’t 0? Her/His displacement is 0, so her/his average velocity should also be 0, but I have people arguing that it is possible for the person’s average velocity to not be 0, or that there is not enough information provided in the question to solve for the answer.

If you consider with respect to earth only, then the answer is zero. But if the point of reference is outside the earth, then the answer will be different. If the frame of reference is outside the solar system, or milky way galaxy then the answer will be different again.
