Scale: 2 inches = 25 miles

1) 1 mile = 2/25 inches

thus, 60 miles = 60 x 2/25 = 4.8 inches

2) 2 inches = 25 miles

thus, 14 inches = 25/2 x 14 miles = 175 miles

I'm sorry can you help me with that last one again it wasn't 14 inches it was 1/4 inches sorry.

You can do this by establishing equality of reasons. In this case we have that, two inches account for 25 miles; and the question is; How many inches, represent 60 miles?

This can be stated as follows:

2 inches → 25 miles

x inches → 60 miles

Or as equality between two reasons:

2/x = 25/60

Solving for x, we have:

x = (60)(2)/25 = 4.8 inches

In Part b, you can use the same procedure, that is:

2 inches → 25 miles

14 inches → x miles

Or, in the form of equal reasons:

2/14 = 25/x

Solving for x, we have:

x = (14)(25)/2 = 175 miles

So, in your map we have the following:

**60 miles are equivalent to 4.8 inches and 14 inches represents 175 miles**.

for 1/4 inch

since 2 inch = 25 miles

1/4 inch = 25/2 x 1/4 miles = 3.125 miles.

hope this helps.
