SUMMARY
The discussion centers on the mathematical function h(t) = 3 + 2sin(0.5236t), which calculates the depth of water in meters as a function of time t (in hours after 7). A ship can only enter the harbor if the water depth is 4.5 meters or more. The correct approach to find the time intervals when the depth meets this requirement involves solving for t using the sine function, specifically identifying the solutions at t = 1.619 and t = 2.293. The final step requires dividing the latter solution by 0.5236 to determine the duration the ship can remain in the harbor.
