Final answer:
Florida has the best access to the ocean for shipping, transportation, and tourism due to its extensive coastline on both the Atlantic Ocean and Gulf of Mexico, as well as its developed ports and tourist attractions.
Step-by-step explanation:
The state that would have the best access to the ocean for shipping, transportation, and tourism is Florida. Unlike Colorado and New Mexico, which are landlocked, and Michigan, which is bordered by the Great Lakes, Florida is surrounded by the Atlantic Ocean to the east and the Gulf of Mexico to the west. Florida's extensive coastline and numerous ports make it an ideal location for oceanic activities. Additionally, it has a warm climate and well-developed tourist attractions, further enhancing its suitability for these purposes.
