    From I and II, speed of boat in still water = 1 (12 + 4) km/hr = 8 km/hr. 2 From II and III, we get: Using average speed = 2xy , we get: 2 x 4 x y = 6 x + y 4 + y 8y = 24 + 6y y = 12. Required speed = 1 (12 + 4) km/hr = 8 km/hr. 2 Similarly, I and III also give the answer. Correct answer is (D).
