Kim is looking at a map with a scale of 1 inch : 18 miles. If the distance between Kim's house and her friend's house on the map is 4 inches, how many miles away is her friend's house?
if 1 inch on the map is 18 miles, then 4 inches would just be 18 * 4 = 72 miles.
hope this helped! please let me know if you are confused about anything i did
