Si circulamos al doble de velocidad, ¿la distancia de frenado aumenta también el doble?

If we drive at twice the speed, does the braking distance also double?

  • ALa distancia de frenado siempre es la misma independientemente de la velocidad.Braking distance is always the same, whatever the speed.
  • BSí, aumenta en la misma proporción.Yes, it increases in the same proportion.
  • CNo, aumenta en mayor proporción.No, it increases in a greater proportion.
Show answer

Correct answer

  • CNo, aumenta en mayor proporción.No, it increases in a greater proportion.
Explanation

If we double the speed, the braking distance becomes 4 times longer. So the increase is not proportional to the increase in speed; it is greater.
