So... Ok... throw out the stuff we don't need... this ship is making 9mph and will take 9.3 (9 hours and 18 minutes) to complete. At 8 gallons per hour it will use 74.66 gallons, and will have roughly have .4 (4/10ths) of a gallon left...
Isn't it 9hrs 20minutes?
72 plus 8/3 gallons
about a third of a gallon left
