Show answer and explanation
Correct answer: depends, among other factors, on the speed at which the vehicle is traveling.
Reaction distance depends on how long you take to react and your speed. Your condition affects that time, and your speed affects how many meters you travel during it. With a reaction time of about 0.75 seconds, that's about 10 meters at 50 km/h and about 25 meters at 120 km/h. In the image, the car keeps moving from the moment the driver sees the ball until they press the brake pedal.
