Yes, it is actual that you can drive 4,500 miles in North America, from Miami to Fairbanks, and English will be the sanctioned oral communication all on the way. But you can drive 7,500 miles south from San Diego, California to Punta Arenas, Chile and Spanish will be the allowed tongue all on the way! (Actually it's 6,537 miles as the corvine bird flies, but I aforementioned 'drive'! Incidentally it's 3,963 miles from Miami to Fairbanks, as the corvine bird space.)
In fact, for the Americas, in vocabulary of the book of numbers of indigenous speakers, the primary languages are Spanish, English, Portuguese and French, in that order! So, unless you go to Brazil or Haiti or Quebec, if you speak some English and Spanish, you can get on moderately nicely. For the full world, Spanish is the ordinal most-spoken language, after English, Chinese and Hindustani. It is wide vocal in Europe.
