A person on earth communicating via radio transmission with an astronaut on the moon asks a question. At the time of transmission, the moon is 3.843.84 × 10105 km from the earth, and the speed of radio waves is 3.003.00 × 10108 m/s. How long must the person on earth wait for a response if the astronaut answers 5.005.00 s after the message is received?
