You have an electric car that you want to use to transport some batteries 1,000 miles. You have 3,000 batteries, but your car can only carry 1,000 of them at once. In addition, for each mile that it travels, the car will need to use up one battery in order to power itself.

How many unspent batteries will you be able to transfer to your destination?

(In reply to answer by chaits)

By varying the distance between stockpiles, you might be able to tweak the number slightly, but I suspect that "250 miles/500 batteries left" is the optimal
