The man and dog both stay on the same bank of a straight river on points A,B respectively which is flowing with V ms¿1 continuous velocity of width a meters. The length of AB is d meters. AB is in the direction of V(V¿u¿v).The man ride the boat across the river such that he can reach the point C which is situated directly opposite to the point A. Show that ,the time taken by him to move from A to C is given by äu2¿V2 seconds.
