You can binary search on the answer, and maintain a segment that everyone can reach. If the segment is non-empty then the value is ok.

    i find function to be unimodal so ternary search is most optimal then binary search.

        by general intution plot will be minima type where at local minima there will be minimum time requird for all peoples to collect at place.

        still can get more precise
