Question

    A train running at a speed of 60 km/h takes 30 seconds

    to cross a pole. Find the approximate time taken by the train to cross a platform whose length is 0.5 times the length of the train.
    A 45 secs Correct Answer Incorrect Answer
    B 75 secs Correct Answer Incorrect Answer
    C 12 secs Correct Answer Incorrect Answer
    D 25 secs Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Length of the train = (60 × (5/18) × 30) = 500 metres Length of the platform = (500 × 0.5) = 250 metres Time taken by train to cross the platform = [(500 + 250) / (60 × (5/18))]= (750 / 16.67) = 45 seconds
