In what way does doubling of the speed of a passenger car influence the braking distance?
Description
The relationship between speed and braking distance is a quadratic function - it increases with the square of the speed.
Explanation
Correct answer: It quadruples the braking distance.
Braking distance increases in proportion to the square of the speed. This means that if you double your speed (e.g., from 50 km/h to 100 km/h), your braking distance will increase fourfold (2 squared = 4). This relationship shows how crucial it is for safety to adjust your speed to the road conditions.
