A submarine started at sea level and descended at a rate of –32 feet per minute for a given period of time, x. Then, the submarine slowed its descent to a rate of –12 feet per minute for another interval that lasted the same amount of time. If the current position of the submarine is, at most, 480 feet below sea level, describe the solution set for the number of minutes the submarine was travelling at each of these different speeds.
