Answer:
75 miles.
Step-by-step explanation:
If 1 inch is equal to 30 miles than we can assume that .5 inches is equal to 15 miles, since .5 is half of 1 and 15 is half of 30.
Since there is 2 ones, we can multiply 30 by 2 to get 60. And if .5 is equal to 15, we can simply add 15 for the .5.
The answer is 75 miles.
Hope this helps!
