If the difference in speed between the overtaking vehicle and the vehicle being overtaken is small, will the time taken to overtake be shorter?

Explanation
Correct answer: No
No. When the speed difference between the overtaking and the overtaken vehicle is small, the overtaking takes longer, not less time. The overtaking vehicle needs far more time to pass the slower one, which extends the time spent in the oncoming lane and increases the risk of a head-on collision.
