Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m about the surface of the water and the fly at the end of the string rests on the water 3.6 m away and 2.4 m from a point directly under the tip of the rod. Assuming that her string ( from the tip of her rod to the fly ) is taut, how much string does she have out ( see given figure)? If she pulls the string at the rate of 5 cm per second, what will the horizontal distance of the fly from her after 12 second?
