8. What is the overall speedup if an enhancement with speedup of 8
can be used 4/5ths of the time? Express your answer as a fraction.
9. Consider enhancing a scalar machine by providing a vector mode,
which is 6 times faster than the normal mode of operation. What
would the percent vectorization need to be to attain an overall
speedup of 3?
