A river of width ω is flowing with a uniform velocity v. A boat starts moving from point P also with velocity v relative to the river. The direction of resultant velocity is always perpendicular to the line joining boat and the fixed point R. Point Q is on the opposite side of the river. P, Q and R are in a straight line. If PQ=QR=ω. The trajectory of the boat is

Q3
Two swimmers leave. A on one bank of the river to reach point B line right across the other back one of the two causes the river along the straight line AB while the other streams at right angle to the stream and then what's the distance that he has been carried away by the street to get to point B. What is the velocity of his walking if both swimmers reached the destination simultaneously? ( The stream velocity = 2 km/h and the velocity of each swimmer w.r.t still water is 2.5 km/h)
