Final answer:
The average distance between a driver identifying a hazard and coming to a full stop when traveling at 30 km/h is approximately 34.17 meters.
Step-by-step explanation:
The average distance between a driver identifying a hazard and coming to a full stop when traveling at 30 km/h depends on several factors, including the driver's reaction time and the braking distance of the car. From the given information, we can assume a reaction time of 0.500 seconds and a braking distance of 30.0 meters.
To calculate the total stopping distance, we need to add the distance traveled during the reaction time and the braking distance. The distance traveled during the reaction time can be calculated using the formula: distance = speed x time. Since the speed is given in km/h, we need to convert it to m/s by dividing by 3.6. Therefore, the distance traveled during the reaction time is: (30 km/h ÷ 3.6) x 0.500 s = 4.17 m. Adding this to the braking distance gives us the total stopping distance: 4.17 m + 30.0 m = 34.17 m.
