Final answer:
The time it takes for a vehicle with closed windows and doors to sink can vary widely, typically between 1 to 10 minutes, depending on many factors. The reference given does not directly correlate with the sinking time of a vehicle.
Step-by-step explanation:
The question seems to be related to the rate at which a vehicle may sink when submerged in water, with closed windows and doors. While the question alludes to an exact time, the time it takes for a vehicle to sink can vary widely based on many factors, including the type of vehicle, the size and shape of the vehicle, the condition of the vehicle, and external conditions such as water currents and temperature.
Without a specific context, providing an exact number of minutes for a vehicle to sink is not feasible. However, for educational purposes, demonstrations in controlled environments suggest that a vehicle may take between 1 to 10 minutes to become fully submerged, depending on the aforementioned variables.
The reference provided about a piece of ice hitting the water in 2.5 seconds is an example of the kind of physics calculation that could be applied to understanding motion in a fluid context. However, this reference does not directly provide information on the time it would take for a vehicle to sink.
