A village is going to build a 320-meter-long dam within 8 days.16 workers built 96 meters within 3 days.According to this calculation,how many workers should be added?

英语类 英数题A village is going to build a 320-meter-long dam within 8 days.16 workers built 96 meters within 3 days.According to this calculation,how many workers should be added?
一个村庄要在8天之内建一座320米长的大坝.已知16个工人3天可以建好96米.那么根据此,还要加多少工人?
96/3/16 =2 （米）一个工人每天能修2米. 320/8/2=20 （个） 工人, 所以还需要加4个工人.

祝你学习进步.

这题不严谨。已经用了3天，建造了96米，也就是剩下的224米要在5天内完成，即每天要建造44.8米。每个工人每天建造两米，所以这5天内每天需要22.4个工人，取整，则需要增加7个工人。
