60 miles an inch.
240 miles = 4 inches
240 divided 4 = 60 miles

you first write a proportion representing the distance between the cities.
4 in. . . . . 240 mi
_____ = ____
1 in. . . . . . x mi
( 4/1 = 240/x)
240 (1) = 4x --cross multiply the fraction. top left times bottom right, top right times bottom left
240 = 4x --solve what you can on either side
60 = x . . . . . . --you want to isolate the variable (get the x by itself), so you have to get rid of four. since 4 is being multiplied, you divide 4x by 4. you have to keep both sides equal, so you have to do the same on the other side. 240 divided by 4 is 60.
240 (1) = 4 (60)
240 = 240
--check your answer, and it works, so
"60 miles = one inch" is the scale

1 inch=240*5280*3 inches
so scale=1:3801600
