Question

    A vehicle travels at 36 km/h and is scheduled to reach its

    destination in 100 minutes. After traveling half the distance, it stops for 10 minutes. What should be the speed for the remaining journey to reach on time?
    A 40 km/h Correct Answer Incorrect Answer
    B 42 km/h Correct Answer Incorrect Answer
    C 45 km/h Correct Answer Incorrect Answer
    D 48 km/h Correct Answer Incorrect Answer
    E 50 km/h Correct Answer Incorrect Answer

    Solution

    Total distance = 36 × (100/60) = 60 km
    Time for half journey = (30 ÷ 36) × 60 = 50 minutes
    Time remaining = 100 – 50 – 10 = 40 minutes
    Required speed = (30 ÷ 40) × 60 = 45 km/h
