After resting they decided to go for a swim. The depth of the water is 10 times Ron's height. Dean is 49 feet taller than Ron. If Ron stands at 8 feet How deep was the water?
1. Ron is 8 feet tall. 
2. 10 times 8 feet is 80 feet. 
3. Dean is 49 feet taller than Ron. 
4. 49 + 8 = 57 
5. Therefore, the water is 57 feet deep.
