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

`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} (1.2)/(2.9)=(5)/(h) \\ h=(5\cdot2.9)/(1.2) \\ h=12.1\text{ ft} \end{gathered}`
