Final answer:
You are required to park no closer than 15 feet from a fire hydrant. The difficulty in finding parking under one minute in an area with a five-minute average search time is indeed surprising. And, while the exact safety distance to cross in front of a moving vehicle can vary, 28 meters might be adequate given certain conditions.
Step-by-step explanation:
The distance required to park from a fire hydrant varies by location and is dictated by local laws or ordinances. Generally, the typical legal distance to park away from a fire hydrant is not less than 15 feet (about 4.5 meters). Parking too close to a fire hydrant poses a hazard as it can restrict access for firefighters during an emergency, potentially delaying their response and firefighting capabilities.
Coming to the model questions provided, if the mean time to find a parking spot is five minutes with a standard deviation of two minutes, finding a spot in under one minute would be significantly less than the mean and could be considered surprising. As for the safety distance to cross the street in front of a moving car, it's not solely based on a fixed number of car lengths but should account for the car's speed, road conditions, and pedestrian's ability to cross efficiently. Nonetheless, considering a car is 28 meters away, this distance may seem sufficient for a pedestrian to cross the road safely if the car is moving at a slow pace.
Lastly, the importance of understanding parking time distribution can help individuals plan their commute better and reduce the stress associated with finding parking, especially during peak hours. Understanding safety distances when crossing the road can also safeguard pedestrians from potential accidents.
