:
The conversion factor to convert km/liter to mpg: 2.352
:
2.352 * 11 = 25.87 mpg
:
%2855%2A3%29%2F25.87 = 6.378 gallons

55*3=165 miles traveled in three hours.
Now you need to convert 11 km to miles or 165 miles to kilometers
1 kilometer = 0.621371192 miles
1 liters = 0.264172052 US gallons
11*.621371192 =11 km in miles
165/6.835083112=24.14016001 liters used
24.14016001 *.264172052= 6.37715561 gallons used for a three hour trip
I probably messed up somewhere.
That seems like too many gallons for such a short trip
165/6.4 that's almost 26 miles to the gallon
