e table below shows the runtime for those programs on three different computers: Program S. The Execution time in seconds Computer A Computer B Computer C Program 1 Program2 Program3 12 20 40 15 20 50 20 20 10 a) Which computer er is fastest according to total exeention time? How many times as fast is it compared to the other two computers? On b) e user has told you that the three programs constitute the bulk of his workload, but he does not run them equally. The every time program 3 runs, and program 2 runs 4 times for every time program 3 runs. execution time with equal numbers of program executions? user wants to determine how the three computers compare when the consists of different mixes of these three programs. That is, program 1 runs 10 times for er is fastest for this workload and by what factor. How does this compare with the total
