Answer: 20 inches

Step-by-step explanation: Let's quickly create some equations to represent what's going on. We can say i are inches and m are miles. Then, 5i=3m because 5 inches represents 3 miles.

5i=3m

5/3i=1m One mile represents 5/3 of an inch/

12(5/3i)=12m We multiply by 12 since we want to know what 12 miles are

60/3i=12m=20i 12 miles is equal to 20 inches

Hope this helps! For practice, if 10 inches represented half a mile on a map, how many feet are represented by 36 miles?
