Q. A train passes a signal post in 10 seconds and a platform in 25 seconds. If the platform is 150 m long, what is the speed of the train?

  • (A) 36 km/h
  • (B) 45 km/h
  • (C) 54 km/h
  • (D) 60 km/h
Explanation by: Admin
Train length = x; Speed = x/10; (x+150)/25 = x/10 → x=75 → Speed = 75/10 =7.5 m/s =45 km/h.
