Final answer:
The minimum distance one must park from a fire hydrant is typically 15 feet. This law ensures emergency services have access to the hydrant. Safety in crossing a road depends on the vehicle's speed and proximity.
Step-by-step explanation:
In regards to the distance one must park from a fire hydrant, the answer varies based on local regulations. However, the most common distance required by law is not less than 15 feet. It is important to adhere to this regulation to ensure that in case of a fire emergency, fire trucks and firefighters have unobstructed access to the fire hydrant. Not following this law might hinder emergency services and could result in a fine.
When determining if it is safe to cross the road with an approaching vehicle, one must consider the speed and distance of the vehicle. If a car is 28 meters away, or approximately the length of 8 cars, whether it is safe to cross will depend on the speed of the car and the width of the road. In general, it is safer to wait until the car has passed unless you are certain you can cross safely before the car reaches you.
