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=(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(87m)/(1cm) \\ \therefore L_(train)=1235.4m \end{gathered}`
