Question 104098
We basically have a ratio here where we can say that the ratio of 600 miles to 10 inches is the same as the ratio of x miles to 18 inches



So the ratio looks like this:


{{{600/10=x/18}}} 



{{{(600/10)*18=x}}} Multiply both sides by 18



{{{10800/10=x}}} Multiply



{{{1080=x}}} Simplify




So our answer is  {{{x=1080}}} 



So the distance between Chicago and Denver is 1,080 miles
