Question

On Tuesday at 2 p.m., the ocean's surface at the beach was at an elevation of 2.2 feet. Winston's house is at an elevation of 12.1 feet. The elevation of his friend Tammy's house is __ times the elevation of Winston's house. Part A How many times greater is the elevation of Winston's house than the elevation of the ocean's surface at 2 p.m.? Part B What is the elevation of Tammy's house? Part C How many times greater is the elevation of Tammy's house than the elevation of the ocean's surface at 2 p.m.? Part D is done. Part E While diving, Winston stopped at a point located halfway between his deepest dive and the ocean's surface. At what elevation was Winston when he stopped halfway?

Answer 1

Winston's house is 5.5 times higher than the ocean's surface at 2 p.m. Tammy's house is 66.55 feet high. Tammy's house is 30.25 times higher than the ocean's surface at 2 p.m.

Step-by-step explanation:

Part A: The elevation of Winston's house is 12.1 feet, while the elevation of the ocean's surface is 2.2 feet. To find out how many times greater the elevation of Winston's house is compared to the ocean's surface, we divide the elevation of Winston's house by the elevation of the ocean's surface. 12.1 / 2.2 = 5.5

Part B: To find the elevation of Tammy's house, we need to multiply the elevation of Winston's house by the factor mentioned in the question. 12.1 * 5.5 = 66.55 feet

Part C: Lastly, we need to find out how many times greater the elevation of Tammy's house is compared to the ocean's surface. We divide the elevation of Tammy's house by the elevation of the ocean's surface. 66.55 / 2.2= 30.25 times

Part D: This part of the question is not provided, so we can skip it.

Part E: To find the elevation at which Winston stopped while diving halfway between his deepest dive and the ocean's surface, we need to calculate the average of the two elevations. (12.1 + 2.2) / 2 = 7.15 feet
