Given that speed of a boat in downstream is 6 Km/hr and in upstream is 4 Km/hr. Then the speed of the boat in still water is?
5 Km/hr
We have known that, if the speed of a boat in downstream is U and in upstream is V. Then the speed of the boat in still water is :- U + V2
And the speed of stream will be :- U − V2
So, here, speed of boat in still water = 6 + 42 = 5 Km/hr
