Does a car traveling the longest time have a greater distance?

No. Distance is dependent on both length of travel and speed of travel.

For example,

If car A leaves location X at a certain time, and travels at 200km/hr for two hours, it travels 400km.

If car B leaves the same location at the same time, and travels 50km/hr for four hours, it travels 200km.

As you can see, car A traveled for half the time car B traveled while doubling its total distance traveled.
