    DIRECTIONS: On the basis of following diagram/ picture answer the questions given below: Which of the following graph does NOT represent constant speed?

    A)            

    B)

    C)   

    D)

    Correct Answer: D

    Solution :

        In a constant speed the change in position of the body remains the same for a particular interval of time. If you break the time axis into small parts and see, the distance travelled in each of these parts is the same in choices A, B and C (it is zero in ?C?). But the distance changes in choice D. Hence, it is the answer.
