# I tried and i tried and still can't get the right answer. A scale on a map shows that 2 inches = 25 miles.  Part AHow many inches on the map represent 60 miles? Part BHow many miles are represented by 14 inch on the map?

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?

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.

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
