The distance to the moon is 238,900 mi. 382,500 kilometers.
So let’s say a person can walk for 70 years. They’d need to walk an average of 3,412 miles a year, which is a little over 9 miles a day.
Most people don’t walk 9 miles a day every day of their life for 70 years, but a person *could.* At 20 minutes per mile, that would be 3 hours of walking a day.
If a person is a runner, and runs 20 miles per day at a rate of 5 mph, so 4 hours a day, they could run to the moon in (oops something is wrong here: 11,945 hours, or 2,986 days of running, why, that’s only 8 years!)
ETA: 11,495 days at 20 miles per day = 32 years.
I would guess that some runners do in fact spend 12,000 hours of their life running, and could have made it to the moon, if only there were a road (and it was not all uphill! And gravity didn’t exist. And oxygen were available. Etc.
