In 1990, the Americans with Disabilities Act (ADA) went into effect. This act made provisions for public places to be accessible to all individuals, regardless of their physical challenges. One of the provisions of the ADA is that ramps should not be steeper than a rise of 1 foot for every 12 feet of horizontal distance. (Lesson 1-3)
a. What is the slope of such a ramp?
b. What would be the maximum height of a ramp 18 feet long?
