Answer: 1 in = 3.6 ft
Step-by-step explanation:
The small car is a model of the large car. The small car is 5 inches long while the large car is 18 feet long.
We currently have a ratio of: [tex]\frac{18 ft}{5 in}[/tex]
We need to get either the 18 or the 5 to one single unit.
18 ft : 5 in
Divide both sides by 5 to isolate 1 inch.
[tex]\frac{18}{5}[/tex] ft : [tex]\frac{5}{5}[/tex] in
Simplify.
3.6 ft : 1 in
We found that the ratio of the scale model is 1 inch of the model is equal to 3.6 ft of the real car.
Therefore, 3.6 ft = 1 in, which is equivalent to 1 in = 3.6ft
