Computer Architecture Questions, please Help!?

1) Consider a one level cache organization. Assume the L1 cache has an access time of 1 ns and a hit rate of .95. Suppose that we can change the cache design such that the hit rate is increased to .97, which also increases the cache access time to 1.5 ns. With conditions(s) must be met for this change to result in improved performance?

2) Consider a single level cache with an access time of 2.5 ns, a line size of 64 bytes, and a hit rate of .95. Main memory has a penalty of 50 ns for the first word (4 bytes) and an access time of 5 ns for each word thereafter. What is the average memory access time?
