Question

Denise lives in a two-story house with a basement. The first story of the house is at ground level. The basement floor is at an elevation of −10.5 feet and the second story floor has an elevation of 12 1/4 feet. Use the absolute value of each elevation to find the distance between the basement floor and the second story floor.

Answer 1

• 22.75 ft

Explanation:

Given

• Elevation of basement = -10.5 ft
• Elevation of first story = 0
• Elevation of second story = 12 1/4 ft

The distance between basement and second story floors:

• |-10.5| + |12 1/4| =
• 10.5 + 12.25 =
• 22.75 ft
