    Question

    A train covers 150 km in 100 minutes. If the speed of

    the train decreases by 25 km/h, find approximate how long it will take to travel the same distance.
    A 2 hours and 13 minutes Correct Answer Incorrect Answer
    B 2 hours and 18 minutes Correct Answer Incorrect Answer
    C 3 hours and 18 minutes Correct Answer Incorrect Answer
    D 1 hours and 28 minutes Correct Answer Incorrect Answer

    Solution

    ATQ, Speed of the train = (150/100) × 60 = 90 km/h New speed of the train = 90 – 25 = 65 km/h So, required time = (150/65) × 60 = 138.46 minutes or approximately 2 hours and 18 minutes
