Marinada '25

[lang=hr] Imamo dva trkača. Prvi trči u rasponu $\left[0 , 20\right] \frac{km}{h}$ dok drugi trči u rasponu $\left[5 , 25\right] \frac{km}{h}$. Kolika je šansa da je prvi brži od drugog? [/lang] [lang=en] We have two runners. The first runner has a speed uniformly distributed in the range \([0,20]\ \text{km/h}\), while the second runner has a speed uniformly distributed in the range \([5,25]\ \text{km/h}\). What is the probability that the first runner is faster than the second runner? [/lang]
