Two people need to finish a work. The first person can finish the work by himself in \(\frac{2}{5}\)hours. At first, the first person does it alone and then 12 minutes later the second person join to work together. Two people work in \(\frac{1}{9}\) hours, then complete the work. How long does it take the second person to finish the work all by himself?
Một giờ người thứ nhất làm được \(1:\frac{2}{5}\) = \(\frac{5}{2}\left(cv\right)\)
=> 12 min người thứ nhất làm được \(\frac{5}{2}.\frac{1}{5}\)=\(\frac{1}{2}\left(cv\right)\)
Số phần công việc còn lại: \(1-\frac{1}{2}=\frac{1}{2}\)
Người thứ hai làm một mình hết: \(1:[(\frac{1}{2}:\frac{1}{9})-\frac{5}{2}]\) =\(\frac{1}{2}\) (h)
