Question

Your model locomotive is 18 inches long. It is an exact model of a locomotive that is 72 feet long. A window on the locomotive is how many times wider than a window on the model?

Answer 1

`72feet=72*12inches=864inches`

ratio:


`18:864`

or:


`1:48`

so window is 48 times wider normaly than in this model

Answer 2

Answer: 4

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

`k=(72)/(18)=4`

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.
