Sean and his family are planning a trip from Columbus, Ohio to Gatlinburg, Tennessee. Sean is trying to plan out the trip ahead of time to get a rough estimate on how much he will spend in gas getting there and back. Sean is looking at an atlas and the key at the bottom shows for every 1 and 1/2 inch on the map is approximately 80 miles of actual distance. Sean measured it to be about 5 and 1/4 inches on the map. How far is the actual distance Sean will drive one way? How far will Sean drive round trip (there and back, no sightseeing)? If Sean's car gets 20 miles per gallon and gas averages about $2.60 a gallon, approximately how much will Sean spend on gas for a round trip? -Help a friend out? Maybe?-
