Question

A model train has a scale of 1.2 in :2.9 ft. If the model train is 5 in tall then how tall is the real train?

Answer 1

Answer:

$h=12.1\text{ ft}$

Step-by-step explanation:

Given the scale of the model train, use proportional relationships to find the height of the real train:

$\begin{gathered} \frac{1.2}{2.9}=\frac{5}{h} \\ h=\frac{5\cdot2.9}{1.2} \\ h=12.1\text{ ft} \end{gathered}$
