Three crews, working together, need to complete a certain job. It is known that the first and second crews together can complete it 36 minutes faster than the third crew alone. In the time it takes for the first and third crews to complete the job together, the second crew can complete only half of the job. In the time it takes for the second and third crews to complete the job together, the first crew can complete $\frac{2}{7}$ of the job.
