Answer: 4

Step-by-step explanation:

Given: The length of a model locomotive = 18 inches

The length of a exact locomotive = 72 inches

The scale factor to scale the model of the locomotive is given by the ratio of the length of the locomotive to the length of the model.

let k be the scale factor, then

[tex]k=\frac{72}{18}=4[/tex]

Hence, the dimensions of the locomotive model is 4 times the dimensions of the model.

Therefore, the locomotive is 4 times wider than a window on the model.
