the speed that a tsunami can travel is modeled by the equation s = 356\\sqrt{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?\n0.32 km\n0.75 km\n1.12 km\n3.17 km
Answer
Explanation:
Step1: Substitute given speed into formula
Given $S = 358\sqrt{d}$ and $S = 200$. So, $200=358\sqrt{d}$.
Step2: Solve for $\sqrt{d}$
Divide both sides by 358: $\sqrt{d}=\frac{200}{358}\approx0.5587$.
Step3: Solve for $d$
Square both sides: $d=(0.5587)^2\approx 0.32$.
Answer:
0.32 km
