Answer:
A speed
In conclusion, speed and velocity are kinematic quantities that have distinctly different definitions. Speed, being a scalar quantity is the rate at which an object covers distance. The average speed is the distance per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change per time ratio.
