1.	A river is flowing with a speed of 1 km/hr. A swimmer wants to go to point C starting from A. He swims with a speed of 5km/hr. at an angle theta. W.r.t. the river flow. If AB=BC=400m at what angle with river tank shou ld swimmer swim?
Answer» `37^(@)` `53^(@)` `0^(@)` `90^(@)` Solution :`(5SIN theta)xxt=0.4` `(5 cos theta+1)t=0.4`
