Oregon is about 400 miles from west to east, and 300 miles from north to south. If a map of Oregon is 15 inches tall (from north to south), about how wide is the map?
A.
20 inches
B.
11.25 inches
C.
16 inches
D.
22.75 inches
We can use proportions to solve this problem. If 300 miles (north to south) is represented by 15 inches on the map, then 1 inch corresponds to 20 miles. Therefore, for the 400 miles (west to east), we would need:
400 miles ÷ 20 miles per inch = 20 inches
Therefore, the width of the map is approximately 20 inches. The answer is A. 20 inches.
