How should you arrange 7 water fountains in a mall to minimize the longest possible walk?

The video tutorial explores the optimal arrangement of water fountains in a circular mall to minimize the maximum walking distance. Initially, the problem is simplified using three fountains, leading to a mathematical approach involving radius and arc calculations. The solution is extended to seven fountains, where a central fountain and six perimeter fountains are used. The tutorial concludes with a discussion on the complexity of the problem and references to further exploration.
