Final answer:
If the visiting team scores at 9:00, the time penalty for the home team at 10:00 would have no effect on the score. If the home team scores at 9:00, the time penalty for the visiting team at 9:30 would have no effect on the score.
Step-by-step explanation:
If the visiting team scores at 9:00, the time penalty for the home team at 10:00 would have no effect on the score. The visiting team would still have their score from 9:00. The time penalty only affects the team's time on the field, not their previous score.
On the other hand, if the home team scores at 9:00, the time penalty for the visiting team at 9:30 would have no effect on the score. The home team would still have their score from 9:00. Again, the time penalty only affects the team's time on the field, not their previous score.
