There are two correct statements here,

1. The car that finishes last has the lowest power.

2. The car with the greatest power travels the greatest distance.

Explanation:

Let us delve into the definition of the terms given, work defines as amount of force being transferred from one object to the other over a distance or displacement of the object. Power is defined as the rate of work being done per unit time. There is a factor of velocity is power. Here, in the above two answers, there are cases of power and work done. The care finishes last have done the work per unit time is less than the rest of the cars. This is same for the second one too. When there is a high power, the rate of work done increases hence, it could travel long.
