Krista is standing at the edge of a long straight beach when she sees Jared drowning. Assume that Jared is at a distance of 76 meters straight out from a point on the beach that is 380 meters from where Krista is standing. Assume that Krista can run at 6.5 meters per second and swim at 1.4 meters per second. Krista runs down the beach toward Jared to a point P on the beach, and then dives into the water and swims to Jared. The
angle at the point P between the beach and the line from P to Jared has a measure of 77 degrees. How long does it take Krista to save Jared?
