Video Summary

Six girls share two bathrooms and aim to finish their morning routine efficiently. With shower times of 9, 11, 13, 18, 22, and 23 minutes, the goal is to minimize total usage time. By strategically assigning longer shower times to the same bathroom and balancing the remaining times, the optimal schedule results in a total time of 49 minutes for bathroom one (with 22, 18, and 9-minute showers) and 47 minutes for bathroom two (with 23, 13, and 11-minute showers). Consequently, they can all have breakfast together at 7:49 AM, 49 minutes after starting.
