Question

Across a horizontal distance of 40 feet, Seaside Bluff has a steep drop. The height of the land at the bottom of the drop is — 240 feet, compared to its height at the top of the drop. What is the average amount that the land's height changes over each horizontal foot?

a. 1/6 ft
b. - 6 ft
c. - 1/6 ft
d. 6 ft

Answer 1

The average change in the land's height over each horizontal foot at Seaside Bluff is 6 feet, representing a decrease in height. the correct option is (d).

Step-by-step explanation:

To find the average change in height per horizontal foot at Seaside Bluff, we need to divide the total change in height by the horizontal distance. The height changes from the top to the bottom by – 240 feet, and the horizontal distance is 40 feet. Therefore, we calculate the average change in height per foot by dividing -240 feet by 40 feet, which equals

6 feet per foot.

Average Change = Change in Height / Horizontal Distance

= 240/40

= 6 ft

Therefore, the average amount that the land's height changes over each horizontal foot is 6 ft. This indicates a steep drop of 6 feet in elevation for every horizontal foot along Seaside Bluff.
