A 110 m long train takes 3 seconds to pass a pole. How long is the platform if the train passes it in 15 seconds? |
440 m 400 m 550 m 450 m |
440 m |
110 m long train takes 3 seconds to pass a pole Speed = 110/3 m/sec The same train passes the platform in 15 seconds, distance travelled = 15*110/3 = 550m The distance = length of platform + length of train 550 = length of platform + 110 length of platform = 440 m The correct answer is Option (1) → 440 m |
