After resting they decided to go for a swim. The depth of the water is w times Dean's height. Dean is x feet taller than Ron. If Ron stands at y feet How deep was the water?
First, we need to find out how tall Dean is. We know that Dean is x feet taller than Ron, and we know that Ron stands at y feet. So, we can set up the equation: 

Dean's height = y + x

Now, we need to find out how deep the water is. The depth of the water is w times Dean's height. So, we can set up the equation: 

Depth of water = w(y + x)
