How long does it take to get to Puerto Rico on a cruise ship?

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.
