The motorbike's tank is capable of holding one drum of fuel (and storing fuel in containers along the way) and can travel one hundred kilometres per drum of fuel expended. It is allowed to go forward, unload some fuel and then return to base using the fuel remaining in its tank. At the base, it can be refuelled and can then set out again. When it reaches any fuel which has been previously stored, it may then use it to partially fill its tank. How far can it go into the desert using ten drums of fuel?
Note: this is inspired by, but is different from, puzzleup question 2.
