Answer:
The total distance is 16.9 m
Explanation:
We understand work in physics as certain force exerted through certain distance. To reach that point below the water, the work done by the diver must be equal to the work done by the water's force of resistance. Therefore, we determine both work expressions and we solve the equation for the diver distance, which is the total distance between the diving board and the stopping point underwater.

When two tectonic plates move in opposite directions, it causes magma to rise, creating a new seafloor.
