Answer
Explanation
A issues a print request after 10 seconds, and the printing is completed 30 seconds after that.
In other words, it takes a total of 40 seconds. Likewise, B is completed after 70 seconds + 30
seconds = 100 seconds. C issues a print request after 80 seconds, but the printing starts after
100 seconds when printing for B is complete. Therefore, the length of time from when A starts
printing until all printing is complete is 130 seconds.
