After day 1: one Porter uses two rations to replanish the other Porter and the Explorer en returns with his remaining ration. After day 2: second Porter gives one ration to Explorer Who now has 4 days worth of food. The Porter returns with two rations. (A ration is food for one man for one day).

but, it never said the porters had to live! So one porter could give all their food to explorer and he could abandon the porter!
