"Rectangular Parallelepiped"s are usually not used to transport fuel.

Though correct, a little wordy. Can you imagine a physical object fitting this definition?

In Europe, we measure the fuel consumption in litres per 100 km. It is quite convenient because I can easily figure out what a litre is (a little bit less than one and half standard wine bottle) and it is not hard to figure out a distance of 100 km. However, any teacher of physics would point out that volume should be measured in [m^{3}] and distance in [m]. After simplification, I get that fuel consumption should be measured in [m^{2}]. What does it represent?
In the U.S., the consumption is measured in miles/gallon. Quite convenient, too, just that in the MKSA system, I get [1/m^{2}]. How do you represent that?

Away with equations!
Is there a solution w/o equations? I mean more simple?

If the boy runs toward the train, the train makes a certain distance.
If the boy runs away from the the train, the train makes the same distance plus the bridge.
In the second case, the boy ran 1/7th of the bridge more, the train the whole bridge more. So the train is seven times faster than the boy. 
Still unsolved... I tried to omit chunks that are contained in other chunks (i.e. TGTGA is there twice and is contained in TGTGACA). I hoped that with the reminder I would be able to build longer chunks. Still too many combinations.
How is it done in praxis?

Borrow money:
ASSETS:
Cash: 100$
Total: 100$
LIABILITIES:
Father: 50$
Mother: 50$
Total: 100$
Buy the phone:
ASSETS:
Cash: 3$
Phone: 97$
Total: 100$
LIABILITIES:
Father: 50$
Mother: 50$
Total: 100$
Return 1$
ASSETS:
Cash: 1$
Phone: 97$
Total: 98$
LIABILITIES:
Father: 49$
Mother: 49$
Total: 98$

one of them can offer a low amount of money (so that it does not matter who starts). In turn, each one can raise or pass. After two subsequent passes, the last one who raised decides where to go, pays the bill and divides the reminder between the other two.

2*n. As we are conditioned to cut a pizza through the centre, each cut will double the number of pieces. As the cuts are random, the pieces will not be of same size.

I know a better variant: 6 butts, you need 3 butts to make a cigarette.

I agree. (I just wanted to be VERY clear.)
