Read the passages and answer the questions that follow. If we want to calculate the average velocity of an object, we must know two things. First, we must know its displacement: the distance it has covered. Second, we must know the time it took to cover this distance. Once we are in possession of this information, the formula for average velocity is quite simple: average velocity = ∆ position / ∆ time. In other words, the average velocity is equal to the change in position (final position - original position) divided by the change in time (final time - original time).
