Shen wants to study about memory access and found out that to main memory there is a "miss" on a cache which takes 25 ns and he leant that there is also a memory access to the cache on a cache "hit" that took 2.5 ns. Shen wonder to know what would be the average memory access time by considering of 65% of processor's memory requesting results in a cache "hit". Try to help Shen by explaining the situation in this case and calculate the average memory access time.
