To calculate the rise of a ramp, it's essential to understand the relationship between the horizontal distance (run), the vertical distance (rise), and the slope of the ramp. A commonly used slope for ramps is 1:12, which means for every inch of rise, there are 12 inches of run. This is crucial for ensuring accessibility, particularly in compliance with ADA (Americans with Disabilities Act) guidelines.

When you have the total length of the ramp in inches, to determine the rise, you can divide that total length by the slope ratio. In the case of the 1:12 slope, if you divide the total length in inches by 12, it will yield the rise in inches. However, in the context of your provided answer regarding option B, it appears there’s some confusion, as the ratio mentioned (16) is typically not standard for accessibility ramps.

The correct foundation for ramp calculations, especially for typical designs, follows dividing the total run by the slope ratio expressed as the distance (for example, 12). The rise is calculated correctly based on this dimensional analysis, emphasizing the unit conversions and understanding of slope ratios in ramp design.

Thus, the choice of measuring the total length in inches divided by a slope factor like
