Vrijeme potrebno za susret u jednakostraničnom trokutu
Zadane duljine stranica jednakostraničnog trokuta (s) i brzine (v) svake životinje označene na vrhovima trokuta saznajte vrijeme nakon kojeg se sretnu ako se počnu kretati prema svojoj desnoj suprotnosti tvoreći putanju.
Primjeri:
Ulazni: s = 2 v = 5
Izlaz: 0,266667Ulazni: s = 11 v = 556
Izlaz: 0,013189
pristup:
Da biste pronašli ukupnu količinu vremena potrebnog da se životinje sretnu, jednostavno uzmite A podijeljeno s početnom brzinom kojom se dva vrha približavaju jedan drugome. Odaberite bilo koja dva vrha i vidjet ćete da se prva točka giba u smjeru druge brzinom v, dok se druga giba u smjeru prve (samo uzmite komponentu duž jednog od bridova trokuta).
