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'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 distance between the deck and the ocean's surface at 1 p. M.?

5.4 feet

Step-by-step explanation:

Let the reference line represents the sea level without any elevation.

At 1 P.M. the ocean surface was at an elevation of 2.2 feet along the line in the figure and the surf shop was  8.2 feet above of this elevated ocean's surface along the line in the figure.

Similarly, at 7 P.M. the ocean surface was at an elevation of -2.4 feet along the line in the figure and the deck in the restaurant was  8.2 feet above of this elevated ocean's surface along the line in the figure.

From the figure, the distance between the deck and the ocean's surface at 1 P.M.= The distance between the lines and .

=5.4 feet

Hence, the distance between the deck and the ocean's surface at 1 P.M. is 5.4 feet.
