Elementary school sixth grade engineering questions 4 and answers以下是4道小学六年级工程问题及答案: **问题1:** 一项工程,甲队单独做需要12天完成,乙队单独做需要18天完成,两队合作需要多少天完成? **答案:** 把这项工程的工作总量看作“1”。 甲队每天完成的工作量(工作效率)为\(1÷12 = \frac{1}{12}\);乙队每天完成的工作量(工作效率)为\(1÷18=\frac{1}{18}\)。 两队合作每天完成的工作量为\(\frac{1}{12}+\frac{1}{18}\),通分得到\(\frac{3 + 2}{36}=\frac{5}{36}\)。 那么两队合作完成这项工程需要的时间为\(1÷\frac{5}{36}=1×\frac{36}{5} = 7.2\)(天)。 **问题2:** 修一条路,甲单独修15小时可以修完,乙单独修20小时可以修完。如果甲乙合修,甲中途休息了3小时,那么从开始到修完共用了多少小时? **答案:** 设从开始到修完共用了\(x\)小时。 把这条路的工作量看作“1”,甲的工作效率为\(\frac{1}{15}\),乙的工作效率为\(\frac{1}{20}\)。 乙工作了\(x\)小时,其工作量为\(\frac{1}{20}x\);甲工作了\((x - 3)\)小时,其工作量为\(\frac{1}{15}(x - 3)\)。 可列方程\(\frac{1}{20}x+\frac{1}{15}(x - 3)=1\), \(\frac{1}{20}x+\frac{1}{15}x-\frac{1}{5}=1\), 通分得到\(\frac{3x+4x}{60}=1 +...
