could someone show me how to write this or set up this equation?2 ships sail from the same port, one sails dew east at 15 mph and the second sailed dew south at 20 mph, how far apart are the ships after 3 hours?

This is the time to use the Pythagorean Theorem.
But first, determine how far they sailed.
15 * 3 = 45
20 * 3 = 60
Then plug those numbers into the theorem and solve for the hypoteneuse.
