Final answer:
To determine the supply of food rations Pi has, one must consider that a human can survive without food for two weeks, which equates to missing 42 meals. The “fuel gauge” analogy suggests that we typically eat before the gauge drops below 70-80% full.
Step-by-step explanation:
The question pertains to determining how long a supply of food rations would last. Assuming that a human can survive for approximately two weeks without food, given that they have adequate water and shelter, we can calculate the number of skipped meals. As there are three meals per day, two weeks would represent 42 missed meals (14 days × 3 meals per day = 42 meals). If we consider our bodies like cars with a fuel gauge, with a meal refilling the gauge, then when we eat regularly, we wouldn’t typically let the gauge drop below a certain level of “fullness” before “filling up” or eating again. For most people, this might correspond to eating before significant feelings of hunger set in, which could be around 70-80% full depending on individual metabolism and eating habits.
