Safe diving hours |
2007-08-16 |
|
From San:
At a popular pier, the average depth of the water at low tide is 1m. The
average depth of the water at high tide is 8m. One complete cycle takes
12h. Given by the equation of y=3.5cosPi/6t+4.5 where y is the height
of the tide in (m) and t is the time in (hour)
*many people dive from this pier during the day. If the water must be at
least 3m deep to dive safely, between what daylight hours should people
dive?
