大家好，我在研读CPU schedule的时候看到以下问题，想请问大家会如何解？
1.Multiple jobs can be run in parallel and finish faster than if they
had run sequentially.Suppose that two jobs, each needing 10 minutes of
CPU time, start simultaneously.How long will the last one take to
complete if they run sequentially?How long if they run in parallel.
Assume 50% I/O wait.
thanks!
