Answer:
Car A has high velocity since its slope is more
both cars doesn't have acceleration since velocity is constant
Hope it helps you

Velocity of a particle is equal to the slope of its displacement-time graph.
v=
t
2
−t
1
s

−s

In the given graph,
v=
4−2
40−20
=10 m/s
Velocity may be positive, negative or zero since it is a vector quantity.
Note: When we draw graph of a vector (say displacement), each component (like component in x-direction) of the vector is drawn on a separate graph. So, for a 2-D motion, two graphs are needed to completely describe the motion of a particle.
