Final answer:
At last quarter moon, high tide will occur closest to 12:00 p.m. and 12:00 a.m.
Step-by-step explanation:
At last quarter moon, high tide will occur closest to the times when the moon is directly overhead or exactly opposite the observer. This happens when the Moon and Sun's gravitational forces combine to create a greater tidal force. In this case, the high tide will occur closer to 12:00 p.m. and 12:00 a.m., which are the times when the moon is directly overhead and exactly opposite the observer, respectively.
