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 = (Change In Y)/(Change In X)`
Or equivalently:

`AVR = (y2 - y1)/(x2 - x1)`
Substituting the values given in the problem we have:

`AVR = (1.5)/(18)`
Rewriting we have:

`AVR = 0.08`
Answer:
the rate of change of the ramp is:

`AVR = 0.08`
