Some mission parameters are at: https://en.wikipedia.org/wiki/Apollo_10#Mission_parameters

The lunar orbit of the LM (Lunar Module) and CSM (Command-Service Module) had a period of 2.15 hours. The interval during which the LM orbited separately from the CSM was 8 hours 10 minutes, or about 3.8 orbits. Thus, at times both craft would have been on the far side of the moon. While the LM was in its lower orbit I don't know how much shorter its orbital period would have been, or whether it "lapped" the CSM during the time between closest approach and redocking.
