If high tide is at noon, the next high tide will be at ... the answer is Midnight

Explained

Explanation:

If high tide is at noon, the next high tide would be close to midnight but not exactly at midnight, as it takes about 12 hours and 25 minutes for the next high tide to occur. So if the first high tide happens at the noon then the next high tide might be around 12:25 AM.

Earth rotates 180/degrees in 12 hours, whereas moon rotates only 6/degrees in 12 hrs, which means every coastal area experience a high tide in every 12 hours and 25 minutes or so.
