Question

A scale model train is 14.2 cm long. Each centimeter represents 87 m on the actual train. How long is the actual Train? A. 6674 B. 66.74 C. 667.4 D. Not given

Answer 1

Scale model train: 14.2 cm

Scale factor:

$\beta=\frac{87m}{1cm}$

The actual train length of the train can be calculated using the formula:

$L_{train}=L_{\text{ scale train}}\cdot\beta$

Then:

$\begin{gathered} L_{train}=14.2cm\cdot\frac{87m}{1cm} \\ \therefore L_{train}=1235.4m \end{gathered}$
