    take if speed is decrease by 20 km/h?
    A 15 min Correct Answer Incorrect Answer
    B 20 min Correct Answer Incorrect Answer
    C 22 min Correct Answer Incorrect Answer
    D 19 min Correct Answer Incorrect Answer
    E 26 min Correct Answer Incorrect Answer

    Solution

    Distance covered in 15 minutes = 20 km.  So the speed of the bus = (20/15) × 60 = 80 km/hr  Reduced speed = (80 – 20) km/hr = 60 km/hr  Time taken to cover 20 km = (60/60) × 20 = 20 min
