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?-

The actual distance is 280 miles

The distance for round trip is 560 miles

It costs $ 72.8 for gas on a round trip

Solution:

Given that,

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

Therefore,

Sean measured it to be about 5 and 1/4 inches on the map

Let "x" be the actual distance

Thus, we can say,

This forms a proportion and we can solve the sum by cross multiplying

Thus the actual distance is 280 miles

How far will Sean drive round trip (there and back, no sightseeing)?

Round trip = 280 + 280 = 560 miles

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?

cost = 28 x 2.60 = 72.8

Thus it costs $ 72.8 for gas on a round trip
