If a person's eye level is h meters above sea level and he can see d kilometers to the horizon, then d = 3.57 h. Suppose the person's eye level is 2.25 meters above sea level. How far can he see to the horizon? Round your answer to the nearest tenth. 22. Suppose that a wave forms in shallow water. The depth d of the water (in feet) and the velocity v of the wave (in feet per second) are related by the equation v = 32d. If a wave forms in water with a depth of 4. feet, what is its velocity?
