Answer: 11 feet.

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

$(x)/(55)=(2)/(10)\\\\\Rightarrow\ x=(2*55)/(10)\\\\\Rightarrow\ x=11\text{ feet}$

Hence, the width of the real boxcar is 11 feet.
