  • 96km/hr. Let the man be in rest. So train relative velocity=150/6=90km/hr So total speed of train =90+6=96km/hr *If the direction of both train and man are same

  • Let the speed of the train be x km/hrbr /Relative speed = (x+6) km/hr = [(x+6)×5/18][(x+6)×518] m/secbr /150/6=(x+6)×5/18 or 5x+30=450 or x = 84 km/hr
