# Let's go boating!

Two boats A and B move away from a buoy anchor at the middle of the river along the mutually perpendicular straight line ; the boat A along the river and the boat B across the river. Having moved an equal distance from the buoy , the boats returned. Find the ratio of time of motion of the two boats $$\frac{t_A}{t_B}$$ ; if the velocity of each boat with respect to water is 1.2 times greater than the stream velocity.
