Answer: D
Explanation: P = W/t
W = F d
When dividing, if you have a large number over a small, you get a large number. We want a small number, so we want the opposite for our P : W/ t formula. We want a small Work and a large time.
Right off the bat, the two with the least time aren't right then.
From there, we can estimate how much work it would take using the W = F d equation. If there is a small distance, there is less work, which is what we want to achieve a small work over large time.
So, the choice with the most time and the least distance should be correct.
