I'm not exactly sure, but the climax is the highest and middle part of the story. So the exposition would probably be the background of why (at first) the narrator didn't like Mr. Duvitch. The rising action would most likely be about catching and replacing the fish.
I believe it is Jackie, because if m/s stands for meters per second then the one with the highest number would be the fastest because they can travel the farthest in the same amount of time.
