A car gets 12 miles per gallon uphill and 24 miles per gallon downhill. If the car goes to the top of Pike’s Peak and back (48 miles uphill followed by 48 miles downhill), what is the car’s gas mileage, in miles per gallon, for the entire trip?
+36916 48 m / 12 m/g + 48 m / 24 m/g = 4 + 2 = 6 g
Total miles 96 miles 96 m / 6g = 16 m/g
+36916 48 m / 12 m/g + 48 m / 24 m/g = 4 + 2 = 6 g
Total miles 96 miles 96 m / 6g = 16 m/g
