Final answer:
The question pertains to the physics of battery capacity and emergency lighting duration, suitable for a high school level curriculum.
Step-by-step explanation:
The question relates to the duration for which emergency lighting, powered by a fully charged battery, can last. This type of question is generally part of physics studies, specifically focusing on electric circuits and energy storage in batteries.
In the question presented, the calculation of runtime for emergency lighting is dependent on the capacity of the battery pack and the power consumption of the lighting. To answer similar problems, one must apply the concept of power (P), which is the rate at which energy is used, and use the formula:
P (Watts) = Energy (Joules) / Time (Seconds)
This question would likely fall into the high school level of education based on complexity.
