A walker'scassette tape player uses four AA batteries in series to provide 6V to the player circuit. The four alkaline battery cells store a total of 200 watt-seconds of energy. If the cassette player is drawing a constant 10mA from the battery pack, how long will the cassette operate at normal power?
