Ascale on a map shows that 2 inches = 25 miles. part a how many inches on the map represents 60 miles? part b how many miles is represented by 1/4 inch on the map?

A = 4.8 inches

B = 3.125 miles

Step-by-step explanation:

We can use proportions to solve this problem.  The map will go on top and real life on the bottom.

2 inches     x inches

=

25 miles    60 miles

We can use cross products to solve

2 * 60 = 25x

Divide by 25

120/25 = 25x/25

4.8 =x

4.8 inches

 Part B

Changing to decimal form

1/4 inch = .25 inches

2 inches     .25 inches

=

25 miles    x miles

We can use cross products to solve

2x = 25*.25

2x = 6.25

Divide by 2

2x/2 = 6.25/2

x = 3.125 miles
