Answer
The single-section ramp would be 0.1875 feet, and the three-section ramp would be 0.0625 feet
The benefits are that it would be easier to climb up a three-section ramp instead of a single section ramp.
Work Step by Step
From the image, we can see the height of the ramps is 5.25 feet, from the floor to the bridge. This will the "rise" of the problem. We can also see in the image that the length of the ramp is 28 feet, which will be the "run" of the problem.
Since the formula for slope is rise/run, we can plug in the two values that we had gotten from the diagram.
Slope = 5.25ft/28ft
Slope = 0.1875 feet
This is the slope to the single-section ramp
To find the slope of the three-section ramp, we can just use divide the single-section ramp by three, since it is 3 sections
Slope= 0.1875ft/3sections
Slope= 0.0625 ft
Therefore, we can see the slope of the three-section ramp is less than the single-section ramp. Since the single-section ramp is steeper, it would be easier to walk up the three-section ramp.
