A Correct answer
Explanation

When a train crosses a cave, distance = train length + cave length. Time taken = 88 seconds. When it crosses a person, distance = train length only. Time taken = 58.64 seconds. So time to cover cave length = 88 - 58.64 = 29.36 seconds. Speed = Cave length / Time difference = 367 / 29.36 ≈ 12.5 m/s. This is a classic relative speed problem.
