We have a problem that runs on a single processor in $80$ seconds. About $30\%$ of the algorithm for the problem is serial and $70\%$ is parallel.

We then run it on a machine with $8$ processors, what result would you expect to see?

It takes less than $80,$ but significantly more than $10$ seconds

It still takes about $80$ seconds

It takes about $10$ seconds

It takes significantly less than $10$ seconds
