Solution
Instructions:
The time difference between two high tides is 12 hours and 25 minutes for the same place on Earth.
Solution:
The revolution of the Moon along with the rotation of
the Earth is considered here.
The place that experienced a high tide at 7 a.m. will
experience another high tide only after 12 hours
and 25 minutes i.e., at 7:25 p.m.
Also, for this same place, it only takes half of the time needed
for the next low tide.
So, the place that experienced high tide at 7 a.m. experience
the next low tide after 6 hours and 12 minutes 30 seconds
i.e., approximately 1:12 p.m.
