First I don’t know if it is a typo or what so im assuming
that you are just repeating the numbers. So 12 in represents 45 mile in the map
so 1 mile can be calculated by using ratio.
Map distance = 1 mile ( 12 in / 45 mile) = 0.27 inch in the
map
my answer is not in your choices, i think, i didnt get your given. so just follow the steps and you will get the correct answer
