A large goose lands in a lake and bobs up and down for a short time. A fisherman notices that the first wave crest created by the goose reaches the shore 7.3 s after the goose first contacts the water. The distance between two wave crests is 65 cm, and in 1.9 s he sees four wave crests hit the shore. How can the fisherman use these observations to determine how far from the shore the goose landed?
