141683 Rain is falling vertically downwards with a velocity of \(3 \mathrm{~km} / \mathrm{hr}\). A man walks in the rain with a velocity of \(4 \mathrm{~km} / \mathrm{hr}\). The rain drop will fall on the man with a velocity of

141684 A \(150 \mathrm{~m}\) long train is travelling from east to west at a speed of \(20 \mathrm{~ms}^{-1}\). A bird is flying from west to east at a speed of \(5 \mathrm{~ms}^{-1}\). How long will the bird take to cross the train?

141685 A train \(100 \mathrm{~m}\) long travelling at \(40 \mathrm{~m} / \mathrm{s}\) starts overtaking another train \(200 \mathrm{~m}\) long travelling at \(30 \mathrm{~m} / \mathrm{s}\). The time taken by the first train to pass the second train completely is-

141688 A person reaches a point directly opposite on the other band of a river. The velocity of the water in the river is \(4 \mathrm{~ms}^{-1}\) and the velocity of the person in still water is \(5 \mathrm{~ms}^{-1}\).
