Question

The scale on a map shows that 2 inches represents 15 miles. Which proportion can be used to find the actual distance, x, represented by 30 inches on the map?

Answer 1

The proportion that can be used is
`(2)/(15)(inches)/(miles)=(30)/(x)(inches)/(miles)`

The actual distance is
`225\ miles`

Explanation:

we know that

The scale on a map is equal to

`(2)/(15)(inches)/(miles)`

so

by proportion

Find how many miles are
`30` inches on the map

`(2)/(15)(inches)/(miles)=(30)/(x)(inches)/(miles)\\ \\x=15*30/2\\ \\x=225\ miles`
