    Sunil covered 50% of his journey at 90 km/h and rest at

    150 km/h. Determine the average speed of Sunil during the entire journey.

    C 102.5 km/h Correct Answer Incorrect Answer
    D 132.5 km/h Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    We know that when distance covered is equal, then average speed is harmonic mean of both speeds. So, average speed = [(2 Ă— 90 Ă— 150)/(150 + 90)] = 112.5 km/h
