A recommended maximum slope for a wheelchair ramp is 1/10 inches. If a business was to install a wheelchair ramp that had a rise of 16 inches, what would be the minimum horizontal length of the ramp in feel?

The maximum wheelchair ramp slope is 1/10. Think of slope as rise over run. So the wheelchair ramp maximum slope has a rise of 1 for every run of 10.

The business ramp has a rise of 16 inches. To get the run of the business ramp, set up a proportion.

16/R = 1/10 where R is the run of the business ramp.

Cross multiply and solve for R.  @lilylovespizza
