Two ships are steaming away from a point O along routes that make a 120°angle. Ship A moves at 14 knots (nautical miles per hour; a nautical mile is 2000 yards). Ship B moves at 21 knots. How fast are the ships moving apart when OA = 5 and OB = 3 nautical miles?© BrainMass Inc. brainmass.com December 16, 2022, 5:38 am ad1c9bdddf
First, find the distance between ships as a function of time. t hours after departure, ship A is 14t miles from point O, and ship B is 21t miles from point O. The distance between ships can be found from the triangle with sides 14t and 21t and ...
