Answer:
The length of the actual train's car is <u>67.5 feet.</u>
Step-by-step explanation:
Given:
The scale of a model train is 1 inch to 13.5 ft.
Now, to get the length of the actual car of the train.
Let the length of actual train's car be ![x.](https://tex.z-dn.net/?f=x.)
And, the length of the car of model train = ![5\ inches\ long.](https://tex.z-dn.net/?f=5%5C%20inches%5C%20long.)
<em>According to the scale of the model train, 1 inch is equivalent to 13.5 ft. </em>
<em>Thus, 5 inches is equivalent to </em>
<em />
Now, to get the length of actual train's car using cross multiplication method:
![\frac{1}{13.5} =\frac{5}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B13.5%7D%20%3D%5Cfrac%7B5%7D%7Bx%7D)
By cross multiplying we get:
![x=67.5\ feet.](https://tex.z-dn.net/?f=x%3D67.5%5C%20feet.)
Therefore, the length of the actual train's car is 67.5 feet.
