    Answer: (1) 40 min

    Explanation:-
    The speed of a man = 4 kmph
    Time taken by a man to covered the total distance = 2 hrs 45 min = (2 + 3/4) hrs
    = 11/4 hrs

    Formula-
    Distance = speed x time

    Then, the total distance covered by a man = 4 x 11/ 4
    = 11 km

    If he is running at a speed of 16.5 kmph the man will cover the same distance,
    Then, the time taken by  a man = 11/16.5
    = 110/165
    = 2 / 3 hr
    1 hr = 60 min
    Therefore, 2 / 3 hr = 2 x 60 / 3 min
    = 2 x 20
    = 40 min

    Hence, the answer is (1) 40 min.
