Question

A cliff diving from a ledge that is 90 feet above the surface of the water. The diver reaches a depth of 60 feet under the surface of the water before returning to the surface. What was the total change in elevation from the highest point to the lowest point?

Answer 1

The total change in elevation for the cliff diver is the sum of the height of the ledge above the water (90 feet) and the depth reached under the water (60 feet), which equals 150 feet.

Step-by-step explanation:

The question involves calculating the total change in elevation for a cliff diver from the highest to the lowest point reached during the dive. To find the total change in elevation, we need to add the height of the ledge above the water to the depth reached under the water. The ledge is 90 feet above the surface, and the diver reaches 60 feet below the surface. The total change in elevation is calculated by adding these two distances together.

The total change in elevation is 90 feet + 60 feet = 150 feet. This represents the diver's total vertical distance traveled from the highest point on the cliff ledge to the lowest point reached under the water.
