Question

Consider a group of 5 benchmarks. With an old generation of CPU in the 90s, the execution times of these benchmarks were 10 minutes, 16 minutes, 4 minutes, 1 minute and 8 minutes.

What is the average speedup of the new CPU (comparing to the old CPU)? Note that, you need to determine whether arithmetic mean or geometric mean should be used here.
