The low tides, as well as the high tides, occur two times in a lunar day, on exactly every half a lunar day passed. A lunar day is 24 hours and 50 minutes long, so every next low tide, or high tide, appears after 12 hours and 25 minutes after the previous one. In this situation we have a low tide that has appeared at 5:10 AM on Friday, so in order to calculate when the other low tide will appear we need to add 12 hours and 25 minutes on it, and that will gives the information that the next low tide will appear at 5:35 PM on Friday.
