Final answer:
The subject of this question is Law, and the distance referred to is 10 feet from a fire hydrant.
Step-by-step explanation:
The subject of this question is Law.
According to traffic laws, you cannot stand or park a vehicle within 10 feet of a fire hydrant. This distance is specified to ensure the safety of emergency personnel in case of a fire and to provide easy access to fire hydrants.
To give you an idea of how far this is, the average car length is around 15 feet, so being 10 feet away from a fire hydrant is a bit more than half a car length.
