- go to www.google.com
- click on "maps"
- click on "get directions"
- type "New York" in the first box (the "from" box)
- type "London" in the second box (the "to" box)
- click on "get directions"
- scroll down to step #23
Or just click this link.
If you don't want to do all that, step #23 says, "swim across the Atlantic Ocean 3462 miles". Google Maps expects that step to take you 29 days to complete. Be sure to pack a lunch. :)
