The velocity of water in a river is \(2 \mathbf{k m p h}\), while width is \(400 \mathrm{~m}\). A boat is rowed from a point rowing always aiming opposite point at \(8 \mathrm{kmph}\) of still water velocity. On reaching the opposite bank the drift obtained is

A boat takes\(4 \mathrm{hr}\) upstream and \(2 \mathrm{hr}\) down the stream for covering the same distance.The ratio of velocity of boat to the water in river is.
269995
The width of a river is\(2 \sqrt{3} \mathrm{~km}\). A boat is rowed in direction perpendicular to the banks of river. If the drift of the boat due to flow is 2 \(\mathbf{k m}\), the displacement of the boat is.
1 \(3 \mathrm{~km}\)
2 \(6 \mathrm{~km}\)
3 \(5 \mathrm{~km}\)
4 \(4 \mathrm{~km}\)
