Question 551118
Two ships leave port at noon. One ship sails north at 6 miles per hour and the other sails east at 8 miles per hour. At what rate are the two ships separating 2 hours later?
--------------
Their directions are 90 degs apart, so it's a right triangle.
They separate at {{{(6^2 + 8^2) = 10}}} mi/hr at all times.
