A train 110 m long is travelling at a speed of 58 kmph. The time in which it will pass a passerby walking at 4 kmph in the same direction is
Detailed Explanation:
The relative speed when both move in the same direction is 58 – 4 = 54 kmph = 54 × (5/18) = 15 m/s.
Time = Distance / Relative Speed = 110 / 15 = 22/3 = 7⅓ seconds.
Therefore, the train will pass the passerby in 7⅓ seconds, making Option 3 the correct answer.
