And?? Like WHAT point on each to start with.

OK here is a map of both. Where do you want to plot your point in Florida (big long state on the left) and where do you want your point on the ridge (big long blue thing on the right) Google Image Result for http://www.windows2universe.org/teacher_resources/magnetism/mid_atlantic_ridge_10_inch.jpg Our answers can not be any more specific than what you give us to work with. Keep in mid that thre ridge is the largest geological feature on earth.

Don't you just love it when a person's "question" doesn't have a verb or a question mark? It's like asking the question, "Red ball" or "11 monkeys in a room". Those aren't questions! Neither is "distance from a point on the florida coast to the Mid atlantic ridge". LOL

Now watch them get upset we didn't read their minds to know exactly what they were thinking and give them the answer they were wanting to hear.
