Which pair of graphs represent the same motion of an object

The pair of graphs that represent the same motion of an object is ; ( D )

Given that :

Velocity = displacement / time

From the equation :

   Velocity is directly  proportional to displacement when time is kept constant . therefore increase in displacement will lead to an increase in velocity of an object.

   Meanwhile when time varies ( change in time ) and an object moves at a constant velocity there will  be an increase in displacement.

  Hence we can conclude that the pair of graphs that represents the same motion of an object is graph D
