Really? That seems awfully slow. Did they use the Moon's gravity to speed back up? |
Yes, once they were beyond the transition zone the Moon's gravity would begin to accelerate the CM/LM.

And the related question, how fast does one need to go to maintain a lunar orbit?

IIRC, the CM/LM orbit was about 60 nautical miles. If I did the math correctly the CM/LM velocity would be about 3700 mph.
