Hi,
Here's what I've managed to find regarding trips to the moon. It's from "Exploring the Earth and the Cosmos" by Isaac Asimov.

Apollo 8 spent ten days in space, taking six days to make ten orbits. This works out at 0.6 of a day per orbit, leaving four days for the journey to and from the moon (i.e. 96 hours). Journey speed would average 2,500 mph. Maximum speed around 25,000 mph (escape velocity).

Apollo 10 made 31 orbits.

Apollo 11 was in space for 195 hours (8 days) and spent 21 hours on the moon.

Journey times for 10 and 11 would be similar to 8. There are others that went to the moon after, but at present am unable to find data. Probably a web site somewhere will give details.

Hope this help, Chris Leather.

  Doing some reading up on the moon trip, I see there are comments that the 97
  hours etc of the Earth to the Moon was remarkably close to the actual times
  of some moon circumnavigations.

  Do any of our space buffs have information on the duration of the moon
  circumnavigations? I know there was one by the US and one by the russians,
  but it may not have been manned. Such things as name of ship, course,
  duration.

  Incidentally I see that the longitude of Stones Hill is 5° 7' W. indicating
  that Verne was familiar with the Meridian of Washington.
