Having moved off an equal distance from the buoy the boats returned. Find the ratio of times of motion of boats τA/τB if the velocity of each boat with respect to water is η=1.2 times greater than the stream velocity.

A and B move away from a buoy anchored at the middle of a river along the mutually perpendicular straight lines: the boat A along the rive move with constant velocities v 1 ​ ​ and v 2 ​ ​ . At the initial moment their position vectors are r 1 ​ ​ and r 2 ​ ​ respectively. The condition for particles A and B for their collision is: Two boats Two particles A and B
