25. A ramp for wheelchair access to the gym has a slope of 5% (that is, the ramp rises 5 feet vertically for every 100 feet of horizontal distance). The entire ramp is built on level ground, and the entrance to the gym is 2 feet above the ground. What is the horizontal distance, in feet, between the ends of the ramp ?

Answer and Explanation

Your Answer is

Correct Answer is C

Explanation

For the trigonometry problem, first find the key information given in the problem: for every 100 feet of horizontal distance, the ramp rises by 5 feet. Then for a step that rises 2 feet vertically, you need at least 2/5*100=40 feet of horizontal distance.
