Length of smaller train = 500 metre Speed of smaller train = 97.2 × (5/18) = 27 m/s Length of bigger train = 656 metres Speed of bigger train = 90 × (5/18) = 25 m/s Since, the smaller train is completely obscured by larger train, therefore, extra length of larger train = 656 – 500 = 156 metres Relative speed of trains ‘A’ and ‘B ‘= 27 + 25 = 52 m/s (Since, the trains are running in opposite direction) Required time = 156/52 = 3 second
