ČAS, POTREBEN ZA SREČANJE V ENAKOSTRANIČNEM TRIKOTNIKU

Glede na dolžine strani enakostraničnega trikotnika (s) in hitrosti (v) vsake živali, označene na ogliščih trikotnika, ugotovite čas, po katerem se srečata, če se začneta premikati proti svojemu desnemu nasprotju in tvorita trajektorijo.

Čas, potreben za srečanje v enakostraničnem trikotniku

Primeri:

Vnos: s = 2 v = 5
Izhod: 0,266667

Vnos: s = 11 v = 556
Izhod: 0,013189

Pristop:
Da bi našli skupni čas, potreben za srečanje živali, preprosto vzemite A, deljeno z začetno hitrostjo, s katero se dve točki približujeta druga drugi. Izberi poljubni dve točki in vidi se, da se prva točka premika v smeri druge s hitrostjo v, medtem ko se druga premika v smeri prve (samo vzemite komponento vzdolž enega od robov trikotnika).
