Question

felix built a ramp based on the scale drawing below. if the height of felixs ramp is 6 inches from the ground, how long is the part of the ramp that is on the ground? 1 in. 12 in. 17 in. 72 in. 60 in. 24 in.

Explanation:

Step1: Set up proportion

Let \(x\) be the length on the ground. The proportion is \(\frac{1}{12}=\frac{6}{x}\) (since the ratio of height to ground length in the drawing should equal the ratio in the actual ramp).

Step2: Solve for \(x\)

Cross - multiply: \(1\times x = 12\times6\). So \(x = 72\).

Answer:

72 in.
