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

30 times wider

Explanation:

Answer 2

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

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

`(16)/(40)\ (in)/(ft)`

Remember that

`1\ ft=12\ in`

so

`(16)/(40)\ (in)/(ft)=(16)/(40*12)=(16)/(480)\ (in)/(in)`

Simplify

`(1)/(30)\ (in)/(in)=(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
