Spoiler:
4 days of water in bottles. ride 1 day out (1 day's bottles used) drop 2 days worth of bottles (2nd and 3rd day's bottles used) ride back to start (final days bottles used).

4 days of water in bottles. ride 2 days (2 days bottles used) drop 1 bottle ( 3rd days bottle used) go back to 1 day out (4th days bottle used). Pick up one of two days worth of bottles left from previous time out and use it to get back to start)


so far 1 day out has 1 days supply of water bottles. 2 days out has 1 days supply of water bottles.

4 days of water in bottles. ride one day (use 1 days bottle to get there and pick up the days bottles left there) Ride second day out (use 1 days bottle to get there and pick up days bottles left there)

At this point you still got 4 days water left and only 4 days to go.
