1in =25 mil
17in= 425 mile
17 times 25 = 425
so the total of miles between chicago and st. louis is 425

None of the answers is complete.
What you need to know is how to work such problems. The best way to do that is through unit analysis. Put down the units (inch, mile, pound, kilogram, Newtons, etc.) when you write in the numbers.
For example, scale = 25 mile/inch (25 miles per inch). Distance = 17 inch X scale = 17 inch X 25 mile/inch = 17 X 25 mile (you do the math).
The important thing to note is that the "inch" with 17 and the "inch" with 25 cancel each other out...leaving "mile" in your answer, which is the desired result because you are looking for how many miles between the cities.
The point is this, when working math problems, always put in the units along with the values (the numbers). If you do, and your answer comes out with weird units, you can guess you did the problem wrong. But if you come out with the units you are looking for (e.g., miles), then you can guess you did the problem right.

Honey take the affection goggles off...they are clouding your suggestions. First, do you mean MATH help? 2d, if an inch equals 50 miles and a pair of inches could equivalent one hundred miles then 2 cities seventy 5 miles aside could fall between one inch and a pair of inches...or in different words, one and one-a million/2 inches. Does this sparkling issues up for you??? not extra homework help at present.

? Are you kidding me? How old are you? Can this possibly be as easy as it seems? Surely it took you more time to boot your computer, log onto Yaoo! Andswers, and key in the question than it would have taken just to do it.
1 / 25 = 17 / x
The four answerers below didn't use a proportion.

1in = 25 miles.
17in = 25 x 17 miles
17in = 425 miles.
