Question

An equation for estimating the speed of a tsunami is s=3.1√d where d is the depth of the ocean in meters and s is the speed in meters per second. Find the depth of the ocean in meters when the speed of a tsunami is 250 meters per second. Round your answer to the nearest tenth of a meter. A. 6503.6 B. 7523.7 C. 2402.5 D. 2231.4

Answer 1

A. 6503.6
