hey, what can be the fastest way of solving such questions?
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?
25500 - 23500 = 2000
we just look at the initial and final values
thank you very much
