Two boats A and B move away from buoy anchored at the middle of a river along mutually perpendicular straight lines, th boat A moves along the river and the boat B moves across the river. Having moved off equal distances from the buoy, the boats returned. Find the times of motion of boats i.e. T(A) / T(B) if the velocity of each boat with respect to water is n times greater than the stream velocity.
