Length of smaller train = 600 metre Speed of smaller train = 57.6 × (5/18) = 16 m/s Length of bigger train = 641 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 = 641 – 600 = 14 metres Relative speed of trains ‘A’ and ‘B ‘= 16 + 25 = 41 m/s (Since, the trains are running in opposite direction) Required time = 41/41 = 1 second
