12. A hockey game consists of three 20-minute periods and two 15-minute intermissions. The game starts at 8:00 AM. Because of stops during the game, an additional 30 minutes elapse. At what time will the game end?
Answer: C
The game will end at 10:00 AM.
To determine the end time of the hockey game, we add the duration of the three periods, the intermissions, and the additional elapsed time. The total game time amounts to 60 minutes of play, 30 minutes of intermissions, and 30 minutes of stoppage, totaling 120 minutes, or 2 hours. Starting from 8:00 AM, this leads us to an end time of 10:00 AM.
A) 9:05 AM
This option is incorrect. If we only consider the 60 minutes of play without accounting for intermissions and stoppages, we would arrive at 9:00 AM, but this does not include the additional time required, making 9:05 AM an illogical conclusion.
B) 9:45 AM
This option is also incorrect. While it factors in some playtime, it fails to account for the two intermissions and the 30 minutes of stoppage time, which collectively extend the game duration beyond 9:45 AM.
C) 10:00 AM
This is the correct answer. It accurately reflects the total duration of the game, incorporating the three periods of play, the intermissions, and the extra elapsed time, culminating in a total of 120 minutes starting from 8:00 AM.
D) 9:30 AM
This option is incorrect. It disregards the full duration of stoppage time and the intermissions. Even considering the game time alone, the proper total leads beyond 9:30 AM, making this option inaccurate.
Conclusion
The correct answer is 10:00 AM, as it comprehensively includes all components of the hockey game's timeline. All other options fail to account for the necessary intermissions and stoppage time, resulting in significantly earlier and incorrect conclusions.
