61. The rowers' puzzle. A team of rowers can cover a given distance against the current in $8 \frac{4}{7}$ minutes. In the absence of the current, the same distance is covered in 7 minutes less than it would take to cover it with the current. How many minutes does it take the team to cover the given distance with the current?
61. For \(3 \frac{9}{17}\) min. The team in still water covers \(\frac{1}{5}\) of the total distance per minute, while the current contributes \(-\frac{1}{12}\) of the total distance per minute. The difference and sum of these fractions are \(\frac{7}{60}\) and \(\frac{17}{60}\), respectively. Therefore, the journey against the current will take \(\frac{60}{7}\) (or \(8 \frac{4}{7}\)) min, while the journey with the current will take \(\frac{60}{17}\) (or \(3 \frac{9}{17}\)) min.
