Question

Recall the dunking booth at the Family Night with Principal Berry.
A ball was thrown, the target was hit, and Mr. Berry fell into the water.

This created a local tsunami!
The speed of this tsunami can be calculated using the formula s=3.1⋅√d where d is the depth of the water in meters.
If the speed of the tsunami is 5 meters per second, what is the depth of the water?
A. 1.61 meters
B. 15.5 meters
C. 2.60 meters
D. 3.94 meters

Answer 1

\[d=\frac{ s ^{2} }{ (3.1)^{2} }=\frac{ 5 ^{2} }{ (3.1)^{2} }\]

Answer 2

its D?

Answer 3

No, 5^2/(3.1)^2=2.6 m
