While going from Mumbai to Pune by car, I realized that one of the tyres has two punctures. On the basis of my previous experience, I believed that the first puncture alone would have made the tyre flat in 9 minutes and the second would have done it in 6 minutes. If air leaks out at a constant rate, how long will it take both the punctures together to make the tyre flat?
1
\(3\frac{3}{5}\) mins
2
\(3\frac{4}{5}\) mins
3
\(3\frac{2}{5}\) mins
4
\(3\frac{1}{5}\) mins
