    Answer : Option C

    Explanation :

    Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr.

       = 1-sym-oparen-h1 36 x 5 1-sym-cparen-h1m/sec
    18

       = 10 m/sec.

    Distance to be covered = (240 + 120) m = 360 m.

     Time taken = 1-sym-oparen-h1 360 1-sym-cparen-h1sec = 36 sec.
    10
