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?
Answer & explanation
Correct answer: option 1
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
