The city of Odessa, Texas is building a wheelchair ramp to make their courthouse accessible for persons in a wheel chair. The Am
ericans with Disabilities Act (ADA) requires that a wheelchair ramp have an angle of elevation of 4.8°. The ADA guidelines also allow a maximum run of 30 feet of ramp before installing a rest platform. At the Odessa courthouse, the ramp must rise 2.5 feet to reach the top of the steps. Will they have to install a rest platform on their ramp?
A= 3400t + 600 | given formula 21000= 3400t + 600 | substitute the altitude into the formula 20400 = 3400 | subtract 600 from both sides 6 = t | divide both sides by 3400 6 minutes
