Question

    A boat has a speed of 52 km/h in still water. It takes

    8 hours to travel from point B to point A downstream. The total distance between the two points is 448 km. What is the time taken by the boat to travel from point A back to point B?
    A 9 hours 30 minutes Correct Answer Incorrect Answer
    B 9 hours 20 minutes Correct Answer Incorrect Answer
    C 9 hours 45 minutes Correct Answer Incorrect Answer
    D 8 hours 45 minutes Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let, speed of the stream = x km/h So, (52 + x) × 8 = 448 8x = 448 – 416 8x = 32 x = 4 Therefore, time taken by boat to reach point B from point A = 448/48 = 9 hours 20 minutes
