Consider a single level cache with an access time of 2.5ns, a line of 64B and a hit ratio of 0.95. Main memory uses a block transfer capability that has a first word i.e. 4B access time of 50ns and after that 5ns for each word access. If cache waits until block is copied from MM to the cache and then access from cache,the access time is________(in ns) (upto 3 decimal places)
