Question

A distance of 30 miles on a map is represented by a 2-inch line. If the map is enlarged to 3 times its size, what will be the scale of the enlarged map?

PLEASE HELP!

Answer 1

`(1)/(5)(in)/(miles)`

Explanation:

we know that

The original scale of the map is

`(2)/(30)(in)/(miles)=(1)/(15)(in)/(miles)`

If the map is enlarged to 3 times its size

then

the new scale will be

`(2*3)/(30)(in)/(miles)=(6)/(30)=(1)/(5)(in)/(miles)`
