Question

A wheelchair ramp rises 1.5 feet for every 18 feet of horizontal distance it covers. Find the rate of change of the ramp

Answer 1

By definition the rate of change of a function is given by:
 $AVR = \frac{Change In Y}{Change In X}$
 Or equivalently:
 $AVR = \frac{y2 - y1}{x2 - x1}$
 Substituting the values given in the problem we have:
 $AVR = \frac{1.5}{18}$
 Rewriting we have:
 $AVR = 0.08$
 Answer:
 the rate of change of the ramp is:
 $AVR = 0.08$
