    A 476 m long moving train crosses a pole in 14 sec. The length of a platform is equal to the distance covered by the train in 20 sec. A man crosses the same platform in 7 m and 5 sec. What is the speed of the man in m/s

  • 1.8 m/s
  • 1.4 m/s
  • 1.6 m/s
  • 2 m/s
  • 1.2 m/s
  • Explanation:

    Speed of the train = 476/14 = 34m/s

    Length of the platform = 34×20

    = 680 m 

    ∴ Speed of the man = 680/425 = 1.6 m/s
