Question

Your locomotive is 16 inches long. It is an exact model of the locomotive that is 40 feet long. A window on the locomotive this how many times wider than a window on the model?

Answer 1

Answer:

A window on the locomotive is 30 times wider than a window on the model

Step-by-step explanation:

we know that

If two figures are similar, then the scale factor is equal to divide the length of its corresponding sides

In this problem

the scale factor is

$\frac{16}{40}\ \frac{in}{ft}$

Remember that

$1\ ft=12\ in$

so

$\frac{16}{40}\ \frac{in}{ft}=\frac{16}{40*12}=\frac{16}{480}\ \frac{in}{in}$

Simplify

$\frac{1}{30}\ \frac{in}{in}=\frac{1}{30}$

That means----> 1 unit in the model represent 30 units on the locomotive

therefore

A window on the locomotive is 30 times wider than a window on the model
