Question $15$

Assume an algorithm takes $6\mathrm{.}3$ seconds to execute on a single $2\mathrm{.}6$ GHz processor. $47\%$ of the algorithm is sequential. Assume that there is zero latency and that the remaining code exhibits perfect parallelism.

How long $($in seconds$)$ should the algorithm take to execute on a parallel machine made of $62\mathrm{.}6$ GHz processors? Round answers to one decimal place $($e$.$g$.$ for an answer of $17\mathrm{.}214$ seconds, you would enter $17\mathrm{.}2).$
