Chinook salmon are able to move upstream faster by jumping out of the water periodically; this behavior is called porpoising. Suppose a salmon swimming in still water jumps out of the water with a speed of 6.26 m/s at an angle of 30°, sails through the air a distance L before returning to the water, and then swims a distance L under water at a speed of 3.70 m/s before beginning another porpoising maneuver. Determine the average speed of the fish.
