How far will 500 litres of fuel haum 200 kg?

Question

1 litre of fuel will haul 100 Kg 900 km. How far will 500 litres of fuel haul 200 kg?

Answer 1

keeping all factors linear, which wouldn't be the case in real life, then if 1L can haul 100kg 900 km, it can be calculated that 200 kg will travel 450 km on 1 L of fuel.  500 L should then be able to pull that 200 kg (500 x 450) 225,000 km.  

Of course, that doesn't allow for the fact that the 500 L of fuel will itself weigh 400+ kg at the start, which would affect the distance traveled
