Eight-thirty 5583

Five minutes before eight-thirty in the evening, Michal sent photos from his vacation in the Beskydy for retrieval via the Happy Foto e-shop. He had uploaded 1/10 (one-tenth) of photos in 3 minutes. Will he have time to upload and send the photos by 8 PM when the discount event ends? It takes 10 seconds to send a photo file.

t = 19:55 hh:mm

Step-by-step explanation:

$$\begin{gathered} t_1=19+25/60=\frac{233}{12}\doteq 19.4167 \\ t=t_1+10\cdot 3/60=19.4167+10\cdot 3/60=\frac{239}{12}\doteq 19.9167\text{hh}:\text{mm} \\ t<20:00 \end{gathered}$$
