How long did it take for a message sent from Earth to reach the first astronauts on the way to the moon when they were still 10600 km away from the moon?
The time for the message to reach them should equal the speed of the message divided by the distance the message had to travel. The message would have been a radio wave so travelled at the speed of light, 300,000,000 meters per second. So all you need to know is the distance it had to travel. That will be the distance from the surface of the Earth to the Moon (in metres) minus 10,600,000.
