I have two questions. On Monday at 1 p. m., when the ocean's surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean surface. At 7 p. m. when the ocean's surface with an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 ft above the ocean surface. How many feet apart are the two ocean elevations. What is the elevation of the deck where Winston ate dinner
