Assume an algorithm takes 4.6 seconds to execute on a single 3.5 GHz processor. 52% 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 4 3.5 GHz processors? Round answers to one decimal place (e.g. for an answer of 17.214 seconds, you would enter 17.2)
