The area under the velocity$-$time graph gives the value of

Two cars $A$ and $B$ have their displacement-time graph as given below. Which car has a greater velocity?

$A$ body moves with a velocity of $2\, m s^{-1}$ for $5\, s$,then its velocity increases uniformly to $10\, m s^{-1}$ in the next $5\, s$. Thereafter,its velocity begins to decrease at a uniform rate until it comes to rest after $5\, s$.
$(i)$ Plot a velocity-time graph for the motion of the body.
$(ii)$ From the graph,find the total distance covered by the body after $2\, s$ and $12\, s$.

The graph given below is the distance-time graph of an object.
$(i)$ Find the speed of the object during the first four seconds of its journey.
(ii) How long was it stationary?
(iii) Does it represent a real situation? Justify your answer.

What conclusion can you draw from the displacement$-$time graph of a body as shown below?

The distance$-$time graph of a body is parallel to the time axis. The body is
