A How many kilometers did Matej run and swim in the time shown?

B How many kilometers did he cycle if he cycled at an average speed of $25 \frac{\mathrm{km}}{\mathrm{h}}$?

C Calculate the average training time per day. Consider that Matej runs $1 \mathrm{~km}$ in an average of $4.5 \mathrm{~min}$ and swims $750 \mathrm{~m}$ in $13 \mathrm{~min}$. Round the results to the nearest minute.
B1 Matej's training for running and swimming is shown in the table:

|  | MON | TUE | WED | THU | FRI | SAT | SUN | Total |
| :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: |
| run[km] | 10 | 12 | 0 | 8 | 13 | 0 | 0 | $43 \mathrm{~km}$ |
| swim[km] | 2 | 2.5 | 3.5 | 3 | 2 | 0 | 4 | $17 \mathrm{~km}$ |

He cycled for $2.5 h$ on Wednesday and $3.5 h$ on Saturday, which is $6 h$ in the week. The distance he cycled is $s=\bar{v} \cdot t=25 \frac{\mathrm{km}}{\mathrm{h}} \cdot 6 \mathrm{~h}=150 \mathrm{~km}$.

The time Matej spent running: $\frac{43 \mathrm{~km}}{1 \mathrm{~km}} \cdot 4.5 \mathrm{~min}=193.5 \mathrm{~min} \approx 194 \mathrm{~min}$. The time Matej spent swimming: $\frac{17 \mathrm{~km}}{0.75 \mathrm{~km}} \cdot 13 \mathrm{~min} \approx 295 \mathrm{~min}$. He cycled for $6 h=360$ min.

The average training time per day $\bar{t}=\frac{194 \min +295 \min +360 \mathrm{~min}}{7} \approx 121 \mathrm{~min}$.
