At 3 PM a ship which is sailing due north at 12 knots(nautical miles/hour) is 5 miles west of a westbound ship which is making 16 knots. a) At what rate is the distance between the ships changing at 3 PM(adsbygoogle = window.adsbygoogle || []).push({});

is it just simply pythagorean theorem of the rates of both ships?

i got the answer as 20 knots

i dont see how related rates would be involved on this

thanks for the help
