Orkut Maths Puzzle

Q. 6 guys can each carry a maximum of a 10 day ration-supply; they are on the edge of a desert; so they could all walk together straight out into the desert for 5 days, then return home. That's clear! But not much fun.

Well, in order to make this puzzle possible, they decide on a plan of action to send one of them as far as possible straight out into the desert, such that this "chosen one" can then return home, naturally!

Their plan uses 2 strategies:
1- hiding spots for supplies
2- guys giving supplies to other guys

And to make your life easier, the hiding and/or remitting of supplies is always at day's end, and in "packets" of one-day-rations.

Their plan is also such that in total, the least possible packets have been hidden. A packet weighs 7 pounds.

Finally, the guys walk at same speed: 23 miles per day.

How many miles was the "chosen" one able to go into the desert, and how many "pounds" were hidden?
