Video Summary

In the problem, three girls and two boys danced together in pairs, with each pair dancing for one minute, and only one pair on the floor at a time. To find the total dance time, we need to count the number of pairs formed. Each girl danced with each boy, resulting in two pairs per girl. Therefore, the first girl has two pairs, the second girl forms another two, and the third girl adds two more pairs, totaling six pairs. Thus, they danced for six minutes overall, making the answer B, six minutes.
