A 180 m long train crosses a platform in 36 seconds and a signal pole in 12 seconds. Find the length of the platform.
Show answer & explanation
Correct answer: C
Explanation
Length of the train = 180 m
Time taken to cross the signal pole = 12 s
Time taken to cross the platform = 36 s
Speed of the train = 180 / 12 = 15 m/s
Distance covered while crossing the platform = Speed × Time = 15 × 36 = 540 m
Length of the platform = 540 − 180 = 360 meters
