Answer:
30.4 feet.
Step-by-step explanation:
We have been given the length of the ramp on the blueprint is 7.6 inches. The scale on the blueprint is 1 inch to 4 feet. We are asked to find the actual length of the ramp.
We will use proportions to solve our given problem as:
[tex]\frac{\text{Actual length}}{\text{Scale length}}=\frac{4\text{ ft}}{1\text{ inch}}[/tex]
Now, we will substitute the scale length of ramp in our proportion as:
[tex]\frac{\text{Actual length}}{7.6 \text{ Inches}}=\frac{4\text{ ft}}{1\text{ inch}}[/tex]
[tex]\frac{\text{Actual length}}{7.6 \text{ Inches}}\cdot 7.6 \text{ Inches}=\frac{4\text{ ft}}{1\text{ inch}}\cdot 7.6 \text{ Inches}[/tex]
[tex]\text{Actual length}=4\text{ ft}\cdot 7.6[/tex]
[tex]\text{Actual length}=30.4\text{ ft}[/tex]
Therefore, the actual length of the ramp would be 30.4 feet.
