To convert 4.17 hours into hours, minutes, and seconds, we break down the decimal part.
The whole number part represents the complete hours. In 4.17 hours, the whole number is 4. So, we have 4 hours.
The decimal part is 0.17 hours. To convert this to minutes, multiply by 60 (since 1 hour = 60 minutes):
$ 0.17 \text{ hours} \times 60 \frac{\text{minutes}}{\text{hour}} = 10.2 \text{ minutes} $
The whole number part of this result is the number of minutes: 10 minutes.
The remaining decimal part from the minutes calculation is 0.2 minutes. To convert this to seconds, multiply by 60 (since 1 minute = 60 seconds):
$ 0.2 \text{ minutes} \times 60 \frac{\text{seconds}}{\text{minute}} = 12 \text{ seconds} $
This gives us 12 seconds.
Combining the whole hours, minutes, and seconds calculated:
4 hours, 10 minutes, and 12 seconds.
A is 120% of B and B is 65% of C. If the sum of A, B and C is 121.5, then the value of C - 2B + A is:

A tyre has 3 punctures. The first puncture alone would have made the tyre flat in 9 minutes, the second alone would have done it in 18 minutes, the third alone would have done it in 6 minutes. If the air leaks out at a constant rate, then how long (in minutes) does it take for all the punctures together to make it flat?
