Answer:
x=330 miles
Step-by-step explanation:
We can use proportions to solve this problem. Put the map distance over the real life distance.
1 1/4 inches = 1.25 inches in decimal form
1 1/8 inches = 1.125 inches in decimal form
1.25 inches 4 .125 inches
--------------------- = ---------------------
100 miles x miles
Using cross products
1.25x = 4.125 * 100
1.25x = 412.5
Divide by 1.25 on each side
1.25x/1.25 = 412.5/1.25
x=330 miles
