For this question, you must first calculate the thinking distance and the hazard braking distance. At 50 km/h, the thinking distance is 50/10 x 3 = 15. So, there are 15 meters of thinking distance. The hazard braking distance is determined by the following calculation: [(50/10 x 50/10) / 2] = 12.5. 50 km/h is the right answer.
