The inside volume of a house is equivalent to that of a rectangular solid 15.0 m wide by 23.5 m long by 2.5 m high. the house is heated by a forced air gas heater. The main uptake air duct of the heater is 0.27 m in diameter. What is the average speed of air in the duct if it carries a volume equal to that of the house's interior every 15 minutes? Express your answer rounded to one decimal place.
