Maria needed 6 gallons of gas to fill her car's gas tank. The mileage odometer read 31,100 miles. When the odometer read 31,290, Maria filled the tank with 10 gallons. At the end of the trip, she filled the tank with 17 gallons, and the odometer read 31,630 miles. How many miles per gallon did she get for the entire trip?
---
Total miles: 31630-31,100 = 530 miles
----
Total gas:: 10 + 17 = 27 gallons
---
Miles-per-gallon: 530/27 = 19.63
