Solution
The approximate time difference between a High Water (HW) and the immediate Low Water (LW) in a semi-diurnal tide (which is the most common type of tide and it means that there are two high waters and two low waters each day) is about 6 hours and 12.5 minutes. This is because the tidal cycle is approximately 24 hours and 50 minutes, so half of that (from high water to low water or vice versa) is approximately 12 hours and 25 minutes. However, the time from high water to the next low water (or vice versa) is half of that again, which is approximately 6 hours and 12.5 minutes.
