Mammalian nervous system — practice question

The chart shows data for a car travelling at $110\,\text{km h}^{-1}$ with a driver who has not taken alcohol. It indicates the distance the car covers from the moment the driver spots a hazard and responds by applying the brakes, and then the distance it will continue to travel before it comes to a complete stop. If that same driver drinks alcohol before setting off, the distance covered before reacting to the hazard rises by $20\%$. What would the car’s total stopping distance be in that case?

  • A$96\,\text{m}$
  • B$100\,\text{m}$
  • C$111.2\,\text{m}$
  • D$115.2\,\text{m}$
