Ernie says he arrived in New York at about noon and arrives at the Ricardo's at about 9 p.m. after walking from Long Island. The walk from the center of Long Island to East 68th Street where the Ricardo's live is 48 miles and, according to modern Google Maps calculations, would take more than 16 hours to walk. There is no way Ernie walked this distance in 9 hour time frame given, especially since some of that time was spent with him riding the subway.
