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
[tex]\frac{16}{40}\ \frac{in}{ft}[/tex]
Remember that
[tex]1\ ft=12\ in[/tex]
so
[tex]\frac{16}{40}\ \frac{in}{ft}=\frac{16}{40*12}=\frac{16}{480}\ \frac{in}{in}[/tex]
Simplify
[tex]\frac{1}{30}\ \frac{in}{in}=\frac{1}{30}[/tex]
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
