We have the following:
A

We calculate the average rate of these data, as follows:
which means that there is an average rate of 3 points per minute
B
now for the whole game it would be
which means that there is an average rate of 2 points per minute
C.
Since in the first half of the game there is a higher average than the entire game, we can affirm that the game is decided above the first half of the game.
