Question

    Average speed of ‘A’ during a 24-hour journey is 40

    km/h. If he covered the first 150 km of his journey at a speed of 25 km/h, then find the speed at which ‘A’ travelled during the remaining journey.
    A 40 km/h Correct Answer Incorrect Answer
    B 51 km/h Correct Answer Incorrect Answer
    C 45 km/h Correct Answer Incorrect Answer
    D 36 km/h Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Total distance covered by ‘A’ = 24 × 40 = 960 km Time taken to cover 150 km = 150/25 = 6 hours Time taken to cover remaining distance = 24 – 6 = 18 hours So, required speed = {(960 – 150)/18} = 45 km/h
