Answer:
5/8 in.
Explanation:
12 inch : 45 mile = x inch : 1 mile
12/45 = x/1
4/15 = x
4/15 inch
Since that is not one of the choices, there is something wrong with this problem.
Let's try this:
On a map, 1/2 inch represents 4/5 mile.
1/2 inch : 4/5 mile = x inch : 1 mile
(1/2)/(4/5) = x/1
x = 1/2 × 5/4
x = 5/8
Answer: 5/8 in.
