A snorkeler is swimming at a depth of 2 feet below sea level. A scuba diver is swimming at a depth of 30 feet below sea level. What is the difference in depths?
If the snorkeler is swimming at a depth of 2 ft. below sea level, and the scuba diver is also under sea level, but 30 feet, you could subtract 30-2 to get the difference, 28 feet.
