When someone starts from home by motorcycle, if it is specified that driving eastward is positive, and driving westward is negative, the daily driving record is as follows:
(Unit: km)
-7,+4,+8,-3,+10,-3,-6。
Ask how far away from home after the last driving
If the fuel consumption is 0.28 liters per kilometer, how many liters of fuel will be consumed in a day?

According to the meaning of the question: - 7+4+8-3+10-3-6=3.

41 × 0.28=11.48 liters
A total of 11.48 liters of fuel is consumed in one day
