Length of smaller train = 350 metre Speed of smaller train = 43.2 × (5/18) = 12 m/s Length of bigger train = 387 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 = 387 – 350 = 37 metres Relative speed of trains ‘A’ and ‘B ‘= 12 + 25 = 37 m/s (Since, the trains are running in opposite direction) Required time = 37/37 = 1 second
