Question

Most coastal areas on Earth experience two high tides and two low tides every lunar day. What is a lunar day? Our days on Earth are 24-hour solar days, the time that it takes for a specific site on the Earth to rotate from an exact point under the sun to the same point under the sun. A lunar day is a time it takes for a specific site on the Earth to rotate from an exact point under the moon to the same point under the moon. A lunar day is 24 hours and 50 minutes. That means a lunar day is 50 minutes longer than a solar day.
If the first low tide occurs at 5:10 AM on Friday, when will the next low tide occur?
A) 5:10 AM Saturday
B) 5:10 PM Friday
C) 5:35 PM Friday
D) 6:00 PM Friday
