A swimmer swims in still water at a speed`=5km//hr`. He enters a 200 m wide river. Having river flow speed`=4 km//hr` at point A and proceeds to swim at an angle of `127^(@)` with the river flow direction. Another point B is located directly across A on the other side. The swimmer lands on the other bank at point C. from which he walks the distance CB with a speed `= 3 km//hr`. The total time (In minutes) in which he reaches from A to B is
