    Study the given distance-time graph for three cars P, Q and R in a race. Which of the three cars win the race?

    A)  Car P                    

    B)  Car Q   

    C)  Car R                    

    D)  Both Q and R    

    Correct Answer: A

    Solution :

    If a line is drawn parallel to the time axis and corresponding distance axis as given in the graph, the points X, Y, Z, represent some distance travelled by 3 cars. Car P travels this distance in less time than R and Q. Hence, car P has the greatest speed and the winner in the race.
