Final answer:
It is best to delegate vacuuming to roommates while you do the dishes, as you have a greater speed advantage in dishwashing. However, this can cause resentment or unfairness perceptions. Analogous to trade principles, focusing on tasks you perform relatively better can increase overall group efficiency.
Step-by-step explanation:
When living with roommates who are not as efficient as you at cleaning, it is essential to strategically delegate tasks to optimize overall free time. If you are 70% faster at doing dishes and 10% faster at vacuuming than your roommates, assigning them to vacuum could be the most time-efficient strategy.
Furthermore, this scenario can be likened to a trade-related analogy: comparative advantage. Just as countries benefit from specializing in the production of goods they can produce more efficiently and then trading for goods they produce less efficiently, you could apply the same principle to household chores.
