Show answer

Correct answer

  • CLa distancia de frenado aumentará en mayor proporción que el aumento de la velocidad.The braking distance will increase by a greater proportion than the speed.
Explanation

Braking distance increases by a greater proportion than speed. For example, if the braking distance at 40 km/h were 9 metres, at 80 km/h it would be 36 metres: the speed would have doubled, while the braking distance would be four times as long.
