Question

A map provided by an engineering firm has a scale of 1 inch to 2000 feet. If the distance from the starting point for a pipeline to the ending point is 13 1/2 inches how long is the pipe line?

Answer 1

27,000 feet

Explanation:

Let
`x` be the actual length of the pipeline, in feet.

Set up the following proportion:

`\displaystyle\\(1)/(2,000)=(13.5)/(x)`

Cross-multiplying yields
`x=13.5\cdot 2,000=\boxed{27,000\text{ ft}}`
