  1. Speed =d/t.
    =300/40.5=7.40 m/s.
    The speed of the train =7.40X(3600/1000)=26.6 km/hr.

  2. Distance = 150 + 300 = 450
    Time = 40.5 SEC
    Speed = (450/40.5) x (18/5) = 40 K/hr

  3. Total Distance = 150 + 300 => 450

    Time = 40.5

    Speed of Train = (450/40.5) x (18/5) => 40 K/hr
