<span>They approximately traveled 3,349.375 miles. When clicking the red dots you get the distance from Plymouth, England to Plymouth, Massachusettes, which is 5.75. I then multiplied 5.75 with the mileage number that was given in the scale for every one inch, which is 582.5. So, when I multiplied the 5.75 with 582.5 it gave me 3,349.375.</span>
