Answer:
Displacement is to velocity as velocity is to acceleration.
Step-by-step explanation:
Velocity of an object is equal to the change in displacement per unit time. It is given by :

d is the displacement and t is the time taken
Acceleration of an object is given by the change in velocity per unit time. It is given by :

v and u are final and initial velocities
(v-u) is change in velocity
and t is time taken
So, displacement is to velocity as velocity is to acceleration. This is because velocity is related to displacement and similarly acceleration is related to velocity.
