Task 5. A handball team has six players on the field and nine substitutes, goalkeepers are not included. All 15 players in one match played evenly (an unlimited number of substitutions is possible in a handball match, a player can enter and exit multiple times, and there are no player exclusions). How many minutes will each player play if the match lasts 1 hour (two halves of 30 minutes each).
Solution. We have $1 \mathrm{~h}=60 \mathrm{~min}$. On the field, there are always 6 players. $60 \cdot 6=360 \mathrm{~min}$ is the total playing time for all players. The team consisted of 15 players. $360: 15=24 \mathrm{~min}$. Each player played for $24 \mathrm{~min}$.
