[lang=hr] Moramo učitati četiri datoteke veličina $100$ MB, $150$ MB, $200$ MB i $300 MB$. Brzina interneta je $2$ MB/s. U jednom trenutku započnemo učitavanje svih datoteka odjednom. Vrijedi pravilo: dok se istovremeno šalje $n$ datoteka, svaka se šalje brzinom $v/n$, gdje je $v = 2$ MB/s. Nakon koliko sekundi će sve datoteke bit učitane? [/lang] [lang=en] We have to send four files. Their sizes are $100$ MB, $150$ MB, $200$ MB i $300 MB$. Our internet speed is $2$ MB/s. We begin sending all files at once. While $n$ files are uploading concurrently, each file is being transferred at the speed $v/n$, where $v = 2$ MB/s. How long will it take, in seconds, before all four files are finished uploading?
