Answer: 11 feet.
Step-by-step explanation:
Given: A scale model of a boxcar of a train has a length of 10 inches and a width of 2 inches.
The length of the real boxcar = 55 feet.
Let x be the width of the real car.
We know that the corresponding dimension of two similar models are proportional, therefore we have
[tex]\dfrac{x}{55}=\dfrac{2}{10}\\\\\Rightarrow\ x=\dfrac{2\times55}{10}\\\\\Rightarrow\ x=11\text{ feet}[/tex]
Hence, the width of the real boxcar is 11 feet.
