The second page might become its own blog post at some point. The assumption of the Poskim that a Mil is 18 minutes is difficult given the Gemara’s basing a Mil on the walk between Migdal Nuniah and Teveriah, which is a distance of 8 km., or 5 miles. I have a Facebook message in to an Israeli friend of mine who is both an archaeologist and a Talmid Chacham to see if he has any insight into this issue.
