Homework Help: math

Tides are cyclical phenomena caused by the gravitational pull of the sun and the moon. On a particular retaining wall, the ocean generally reaches the 3m mark at high tide. At low tide, the water reaches the 1m mark. Assume that high tide occurs at 12:00 pm and at 12:00 am, and that low tide occurs at 6:00pm and 6:00am. What is the height of the water at 10:30 am?

From 12PM to 12am = 12hrs.

From 12PM TO 10:30AM = 10.5 HRS.

h = (10.5 / 12)3m = 2.625m.
