There is a section of the Atlantic Ocean, known as the Bermuda Triangle, where treasure hunters often search for sunken ships. If a salvage team can search 4 square miles of ocean per day, how long will it take the team to search the red-shaded region in the diagram?

In order to determine the time it will take for the salvage team to search the red-shaded region in the diagram, we need to know the area of this region.

However, the diagram or any specific measurements for the red-shaded region are not provided, so we cannot calculate the time required.
