Answer:
Since the height of the building is proportional to the number of floors, we can write the ratio of the height of the building to the number of floors as a fraction: height of building : number of floors
For the building with 8 floors, the height is 48 feet (as indicated in the figure). So, we have:
height of building : number of floors = 48 ft : 8
Simplifying the ratio, we get:
height of building : number of floors = 6 ft : 1
This means that for every 1 floor, the building is 6 feet high. So, the unit rate is 6 ft/floor. In other words, each floor of the building is 6 feet high.
