Dobrý večer, potreboval by som vysvetliť domácu úlohu ktorú sa snažím vypracovať správne, no nejde mi to.
Uloha: Janko s Vilom sa dohodli, že v sobotu o 7.00h pôjdu na bicykloch na výlet. Janko zaspal a vyštartoval o hodinu neskôr. Kedy (o koľkej) a po koľkých kilometroch sa kamaráti stretnú? Vieme, že Vilo išiel priemernou rýchlosťou 15 km/h a Janko 25 km/h.
