On Monday at 1pm, 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’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
What was the net change in the elevation of the ocean’s surface from 1 p.m. to 7 p.m.?
Answer:
-4.6 ft
Step-by-step explanation:
The question is asking for the net change in the ocean's surface elevation, so we can ignore the parts of the question that mention his own elevation at the time of the measuring. We can see at 1, the elevation was 2.2, and at 7, the elevation was -2.4. The net change is the whole change over the period of time, so we just need to find the difference between the two. Adding them together gives you the distance from each elevation the sea's surface was, which is -4.6 ft as the elevation decreased
