The day before the Ching Ming Festival, a fourth-grade student from a certain elementary school went to the Martyrs Cemetery to sweep graves. The students lined up in a row about 60m long, departed from the school at 8:42, and arrived at the Martyrs Cemetery at 9:00. It is known that it takes 2 minutes for the whole team to pass through an 80m long bridge from start to finish. How many kilometers is it from a primary school to the Martyrs Cemetery?
清明节前一天，某小学四年级同学去烈士陵园扫墓．同学们两人一排排成约60m长的队伍，8：42从学校出发，9时到达烈士陵园．已知整个队伍从头到尾途经一座80m长的桥用时2分钟．某小学到烈士陵园有多少千米？
