1 = left in canteen
2 = canteen leaked over 2 hours
3 = drank during mile 6
4 = drank during miles 1 - 5
------------------------------------------
10 cups total

4 cups / 5 miles = 4/5 cups per mile

3 drank in 6th mile
2 cups leaked in 2 hours

4 remaining cups that were drank in first 5 miles

4 cups in 5 miles = 4/5 cups/mile
