ANSWER
6.2 inches
EXPLANATION
The distance between Chicago and New Orleans is 927 miles.
The atlas uses a ratio 1 inch : 150 miles.
To find the distance of the two places, we have to compare with the ratio.
Let the distance between the two places on the atlas be x inches.
So, we have that:
[tex]\begin{gathered} 1\text{ : 150 = x : 927} \\ \Rightarrow\frac{1}{150}\text{ = }\frac{x}{927} \\ \text{Cross multiply:} \\ 927\cdot\text{ 1 = 150 }\cdot\text{ x} \\ =>\text{ x = }\frac{927}{150} \\ x\text{ = 6.18 inches }\cong6.2\text{ inches} \end{gathered}[/tex]The distance between Chicago and New Orleans on the map is 6.2 inches.
