To find the time it takes for the water level to drop 1 foot, first calculate the volume of water that needs to be leaked out, which is the surface area of the pool (24 feet * 8 feet) times the drop in water level (1 foot), equaling 192 cubic feet. Since the water leaks at a rate of 0.40 cubic foot per minute, divide the total volume by the leak rate (192 cubic feet / 0.40 cubic foot per minute) to get 480 minutes. Converting minutes to hours (480 minutes / 60 minutes per hour) gives 8 hours.
