It basically takes 1.5 seconds for a message to get to the moon or vice versa. But then the recipient STARTS hearing the message, must listen, then respond. So from the END of each message, there is 1.5 seconds, and then ANOTHER 1.5 to get the return message BEGINNING and then the length of the return message.
NONE of the recordings that I've heard have a three second delay.
The moon is 225k miles away. The speed of light in miles per hour is 6.702 x 10^-8 miles/hr.
