Chapter One

If the computer system has three components a, b, and c that can be improved, their component speedup ratios are 30, 30, and 20, respectively. If components a and b account for 30% and 30% of the total execution time respectively. To achieve a speedup of 10 for the overall system, what fraction of the total execution time should component c take?
