A local diner must build a wheelchair ramp to provide handicap access to the restaurant. Building codes require that a wheelchair ramp must have a maximum rise of 1 in. for every horizontal distance of 20 in.

A) What is the maximum allowable slope for a wheelchair ramp?
B) Assuming that the ramp has a maximum rise, find a linear function H that models the height of the ramp above the ground as a function of the horizontal distance x?
C) If the space available to build a ramp is 190 in. wide, how high does the ramp reach?
