Another riddle
RAY: This puzzler was sent in by a young lady named Sarah Zimmerman, age 13. I had to mess around with it a little bit, but she did a pretty good job. Here it is:
A pilgrim needs to make a journey on foot between Casablanca and Marrakesh, to deliver movies to the new Marrakesh multiplex. It's an arduous and dangerous trip at best, and it takes six days. The most a traveler can carry for food and water is four days' worth.
TOM: I hope there's a hotel someplace in between.
RAY: There are no hotels. Here's the question: How many people must start out together, so that one of them can make it all the way to Marrakesh from Casablanca?
One other thing: the others who start out along with the pilgrim? They can't die along the way.

Any ideas? State your reasoning too...

2 with him.
1 walks for a day, then drops off 2 days water and turns round.
the second pics up one days water and so does the pilgrim, so they both have 4 again.
then the second one turns round after another day, leaving 1 days water for the pilgrim, who then has days water and is 4 days away.
Thats least number of people i can come up with anyway.
