Given information: A wheelchair must be at least 12 ft. long for each foot of height. Formula used: An equation that equates two ratios or rates is called a proportion. Therefore, if b≠0 and d≠0, then: ab=cd is a proportion. Calculation: As it is provided that a wheelchair must be at least 12 ft. long for each foot of height. Let x represent the minimum acceptable length of the ramp for 123 ft. of height. Set up a proportion by writing two equivalent ratios: 112=123x Multiply by LCD, that is 12x, 12x×112=123x×12x x=12(123) Solve the resulting linear equation, x=12(53) x=4(5) x=20 Hence, the minimum acceptable length is 20 ft..
