Question

The speed that a tsunami (tidal wave) can travel is modeled by the equation where S is the speed in kilometers per hour, and d is the average depth of the water in kilometers. A tsunami is traveling at 140 km/hr. What is the approximate average depth of the water?

Answer 1

Answer:

The answer is 0.155 km.

Answer 2

Answer:

The average depth of the water will be 0.155 kilometers or 155 meters.

Step-by-step explanation:

The speed at which the tsunami waves travel is $S=356\sqrt{d}$. Here S is the speed in kilometers per hour and d is the average depth of the water in kilometers.

Now, it is given that the wave travels at the speed of $S=140\rm km/hr$.

So, the average depth of the water will be,

$S=356\sqrt{d}\\140=356\sqrt{d}\\\sqrt{d}=0.393\\d=0.155\rm km$

Therefore, the average depth of the water will be 0.155 kilometers or 155 meters.
