A fifth-grade student from primary school went to visit a science and technology exhibition. 422 people lined up in two columns. The distance between the two adjacent rows was 0.5 meters, and the team walked 65 meters per minute. Now to cross a bridge with a length of 1065 meters, how many minutes will it take from the time when the first two people get on the bridge to when the last two people leave the bridge?
一实小五年级同学去参观科技展览，422人排成两路纵队，相邻两排前后各相距0.5米，队伍每分钟走65米．现在要通过一座长1065米的桥，从排头两人上桥到排尾两人离开桥，共需要多少分钟？
