Final answer:
The game was 6 times longer than the warm-up.
Step-by-step explanation:
To find out how many times longer the game was than the warm-up, we need to divide the game time by the warm-up time. Given that the warm-up was 8 minutes and the game was 48 minutes, we divide 48 by 8:
48 / 8 = 6
Therefore, the game was 6 times longer than the warm-up.
