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.
