Assume that we are considering enhancing a machine by adding vector hardware to it .when a computation is run in vector hardware to it.When a computation is run in vector mode on the vector hardware, it is 8 times faster than normal mode of execution. we call the percentage of time that can be spent using vector mode the percentage of vectorization

1. What is the speedup if the percentage of vectorization is 50 %?

2. What percentage of vectorization is needed to achieve a speedup of 2?

3. What percentage of the computer run times is spent in vector mode if a speedup of 2 is achieved?
