Question

The scale on a map is 2cm = 15miles. Dave measures the distance to the next town at 7cm. How many miles away is the next town?

Answer 1

Try 15 times 7 which is 105 miles.....I believe is the correct answer

Answer 2

`52.5\ miles`

Explanation:

we know that

The scale on the map is equal to

`(2)/(15)(cm)/(miles)`

so

by proportion

Find how many miles are
`7\ cm` on the map

`(2)/(15)(cm)/(miles)=(7)/(x)(cm)/(miles)\\ \\x=15*7/2\\ \\x=52.5\ miles`
