A submarine is at an underwater depth of 600 feet. It then rises 100 feet, dives 500 feet, and finally dives another 300 feet. What is the submarine's final depth?
First the submarine is 600ft underwater. Then it rises 100ft to be 500ft underwater. Next it dives 500ft to be 1000ft underwater then 300 more to be 1300ft underwater. Hope this helps!
