How long would it take at sea from okinawa japan to sidney autralia?

Question:

if i was to take a cruse on ship from okinawa japan all the way to sidny australia how long would it take.

Answer:

It's about 4000 miles. Ever heard of a 4000 mile cruise?

And now, back to reality. If you are really interested in determining an hypothetical answer to your question, find out both the top speed of a European barn swallow in full dive and the average speed of the typical cruise ship. Use one of those rates in the equation T=D/R and there you go. Hint: The European barn swallow dive rate is just for fun.)
