Final answer:
The elevation of Winston's house is 5.5 times greater than the elevation of the ocean's surface at 2 p.m.
Step-by-step explanation:
To find how many times greater the elevation of Winston's house is than the elevation of the ocean's surface, we need to calculate the ratio of the two elevations. The elevation of the ocean's surface is 2.2 feet, and the elevation of Winston's house is 12.1 feet.
Therefore, to find the ratio, we divide the elevation of Winston's house by the elevation of the ocean's surface: 12.1 / 2.2 = 5.5.
Therefore, the elevation of Winston's house is 5.5 times greater than the elevation of the ocean's surface at 2 p.m.
