1. A team of 16 people participates in a sports tournament. The rules stipulate that there must always be 11 players on the field for each team and that, during each match (which lasts 90 minutes) all 16 members of each team must play the same number of minutes. For how many minutes will each player be on the field during the match?
(A) less than 57
(B) between 57 and 60
(C) between 60 and 63
(D) between 63 and 66
(E) more than 66
## Problem 1. The answer is (C).

The total number of minutes played by the members of each team during a match is $90 \cdot 11=990$. These 990 minutes must be evenly divided among the sixteen members of the team. Each player will therefore be on the field for $990 / 16=61.875$ minutes.
