Consider a direct mapping single$-$level cache with an access time of $2\mathrm{.}5$ns$,$ a linesize of $64$ bytes, and a hit ratio of H$=0\mathrm{.}95.$ Main memory uses a block transfercapability that has first word $(4$ bytes$)$ access time of $50$ns and an access time of $5$ns for each word thereafter.a$.$ What is the access time when there is a cache miss? Assume that the cachewaits until the line has been fetched from main memory before reexecutes for a hit
