# The speed that a tsunami can travel is modeled by the equation S=356√d , where S is the speed in kilometers per hour and d is the average depth of the water in kilometers. What is the approximate depth of water for a tsunami traveling at 200 kilometers per hour A. 0.32 km B. 0.75 km C. 1.12 km D. 3.17 km

S = 356√d 200 = 356√d √d = 200/356 = 0.5618 d = 0.5618^2 = 0.316 km d = 0.32 km.
