After resting they decided to go for a swim. The depth of the water is 15 times Dean's height. Dean is 4 feet taller than Ron. If Ron stands at 13 feet how deep was the water?
There is no definitive answer to this question as the depth of the water would likely vary depending on the location. In general, however, it is safe to say that the water would have been at least several feet deep in order to accommodate the large number of ships that were involved in the Battle of the Atlantic.
