Marinada '24

[lang=hr] Ivan se biciklom dovezao iz hotela Ankaran do restorana Adria. Trebao je stići točno u 15 sati, ali je $\frac{2}{3}$ planiranog vremena potrošio na prelazak $\frac{3}{4}$ puta. Nakon toga je vozio sporije i stigao je na cilj točno na vrijeme. Koji je omjer brzina na prvom i drugom dijelu Ivanova puta? [/lang] [lang=en] Ivan rode his bicycle from the Ankaran hotel to the Adria restaurant. He was supposed to arrive exactly at 3 p.m., but spent $\frac{2}{3}$ of the planned time crossing $\frac{3}{4}$ of the way. After that, he slowed down and arrived at the restaurant exactly on time. What is the speed ratio of the first and second part of the trip? [/lang]
