The speed that a tsunami can travel is modeled by the equation s=356sqrtd , 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

Option A is the correct answer.

Step-by-step explanation:

S = 356

Making the subject D by squaring both sides ,we get

                  Dividing  both sides by ,we get

           D =

                 here S = 200 km/hr

            D =

               on simplifying it ,we get

                D = 0.3156 KM

                             or

                   = 0.32 km

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept
