>>84057It took me a while but it's just idiotic wording made to trick people.
The truck travels 50% of the time at 40 kmh, then 50% of the time at 80.0 kmh.
The car travels 50% of the _distance_ at 40.0kmh, then 50% of the distance at 80.0 kmh.
The car thus spends 2/3rd of the time at 40 kmh and 1/3rd of the time at 80.0 kmh
This means the truck will be there faster.
