Answer: This is a difficult question, as cruise ships have different top speeds, and what route would the ship take? Can it fit through the Panama Canal? Are you asking about the length of a World Cruise which includes stops at many ports, or simply how long would it take a ship to travel from New York, go around the world, and get back to New York?World Cruises are typically in the neighborhood of 80 - 110 days or even longer, depending on if it truly starts and stops at the same port, and the number and length of port calls. Some World cruises start on the West Coast of the U.S. and end on the East Coast. Others start in New York and end in Southampton.

Answer: The distance from New York to Puerto Rico is 1601 miles or 1391 nautical miles. If you were traveling on a cruise ship, at the rate of 35 knots, it would take 1day, 15hrs and 44min to reach Puerto Rico.
T=D/R (time is equal to the distance divided by the rate) is the formula used to find the answer.
