Motion is a change in position with respect to a reference point.
Distance and displacement, speed and velocity,and acceleration are ways to describe motion.
Distance is a scalar quantity having magnitude but no direction while displacement is a vector quantity having both magnitude and direction.
Average speed refers to the total distance travelled divided by the total time and velocity is displacement divided by total time of travel.
A speedometer measures instantaneous speed/velocity.
