According to Apollo by the Numbers (NASA SP-2000-4029), Entry, Splashdown, and Recovery section on page 305, distances traveled were

Apollo 8: 504,006 nautical miles

Apollo 15: 1,107,945 nautical miles

I assume that as the section refers to Entry, Splashdown and Recovery, that the data refers to the CM only.

There is a footnote (#57) which states that the data on page 305 is "Compiled from mission reports, USN Historical Office data, Apollo Program Summary Report (JSC-09423) and other sources". So perhaps that might give you further scope for investigation.

If you're going to talk about Apollo, are you including Skylab and ASTP? For what it is worth, there were roughly 2,500 hours of spaceflight aboard Apollos 7-17. You decide what sort of average speed you want to do.

There were roughly 4,100 hours of spaceflight during Skylab. I realize that there was some time during which the three crews were accelerating and decelerating, but assuming an average of 17,500 mph (which I think is a little fast) then roughly 71,820,000 miles were traveled during Skylab. ASTP lasted roughly 217 hours, which times 17,500 mph gets you to roughly 3,798,000 miles.
