Question

The scale factor is 5:8. What is the actual length of if the model is 1.5 meters?

Answer 1

Given:

The scale factor is, 5/8

The model length is, 1.5 m.

Taking the proportion we have,

`(5)/(8)=(1.5)/(x)`

Here, x is the actual length and can be calculated as,

`\begin{gathered} 5x=1.5m*8 \\ 5x=12\text{ }m \\ x=(12m)/(5)=2.4\text{ m} \end{gathered}`

The actual length is 2.4 m.
