    The displacement-time graphs of two bodies A and B are shown in figure. Which of the following statements is correct?

    A) A is moving faster than B.

    B) B is moving faster than A.

    C) B is always 20 m behind A.

    D) A is always 20 m behind B.

    Correct Answer: D

    Solution :

    As clear from the distance-time graph, B has already covered 20 m distance while A was at origin. So, A will always be behind B by 20 m as both A and B are moving with constant velocity.
