John scores 2 shots worth 2 points and 1 shot worth 3 points every 4 minutes. He plays for 2 periods. Each period is 12 minutes. How many points does he score? Let's answer step by step:
He played for 2 * 12 = 24 minutes. He gets 2 * 2 = 4 points per minute from the two - point shots. So he scores 4 + 3 = 7 points per minute. There are 24 / 4 = 6 intervals. So he scores 7 * 6 = 42 points. The answer: 42.
