Write the digits that make each true 3-2.=71 5-1 14 78-5=4

So if the map has a scale of 1/4 inch is 250 miles, then what is a full inch. 1/4 times 4 is 1 and then 250 times 4 is 1000. But wait it said 3 inch but we have only one inch so we have to multiply 1000 by three to get 3000. So D would be your answer. Hope I help you understand it!
