The distance between Buffalo, New York and Chicago, Illinois is 600 Miles. On a U.S. road atlas, this distance is represented by 10 inches. On the same atlas, the distance between Chicago and Denver, Colorado is 18 inches. What is the distance between Chicago and Denver?
We will solve this as a proportion;
The first ratio is;
10%2F600
The second would be;
x=distance between Chicago and Denver
18%2Fx
Now make this a proportion;
10%2F600=18%2Fx
Cross multiply;
10x=10800
divide by 10;
x=1080
