A Train Passes A Station Platform In 36 Sec And A Man Standing On The Platform In 20 Sec. If The Speed Of The Train Is 54 Km/hr. What Is The Length Of The Platform? |
|
Answer» Speed = 54 * 5/18 = 15 m/sec. Length of the TRAIN = 15 * 20 = 300 m. Let the length of the PLATFORM be x m . Then, (x + 300)/36 = 15 => x = 240 m. Speed = 54 * 5/18 = 15 m/sec. Length of the train = 15 * 20 = 300 m. Let the length of the platform be x m . Then, (x + 300)/36 = 15 => x = 240 m. |
