Hi!

total distance traveled = about 2000 km

total fuel added = 140L

the last 18L were not used to travel

so 140-18=122L to travel 2000 km

122/2000 = 6,1L/100km

we rounded up the distance traveled so the actual consumption is a little higher, so option D) fits best

thank you for the answer ,sincerely , but how exactly did you infer the total distance travelled is 2000 km?

Hi!

25500 - 23500 = 2000

we just look at the initial and final values
