For a 30-foot driveway with a 5% slope, what is the rise in inches?

• A. 12 inches
• B. 18 inches
• C. 24 inches
• D. 30 inches

Answer: (B)

To determine the rise for a 30-foot driveway with a 5% slope, it is helpful to understand how to calculate the vertical rise based on the percentage of the slope. The slope is defined as the ratio of vertical rise to horizontal run, expressed as a percentage. For a 5% slope, this means that for every 100 units of horizontal distance, there is a 5-unit vertical rise. To find the vertical rise for a 30-foot driveway, you can follow these steps: 1. **Convert the slope percentage to a rise**: A 5% slope indicates a rise of 5 feet for every 100 feet of horizontal run. 2. **Calculate the rise for 30 feet**: You set up a proportion based on this: \[ \text{Rise} = \text{Slope} \times \text{Run} = 0.05 \times 30 \, \text{feet} = 1.5 \, \text{feet} \] 3. **Convert rise from feet to inches**: Since there are 12 inches in a foot, you multiply the rise in feet by 12 to convert to inches: \[ 1.

For a 5% slope, this means that for every 100 units of horizontal distance, there is a 5-unit vertical rise. To find the vertical rise for a 30-foot driveway, you can follow these steps:

1. Convert the slope percentage to a rise: A 5% slope indicates a rise of 5 feet for every 100 feet of horizontal run.

2. Calculate the rise for 30 feet: You set up a proportion based on this:

[

\text{Rise} = \text{Slope} \times \text{Run} = 0.05 \times 30 , \text{feet} = 1.5 , \text{feet}

3. Convert rise from feet to inches: Since there are 12 inches in a foot, you multiply the rise in feet by 12 to convert to inches:
