    hi,
    please , i need the solution of this question from computer system architecture book for morris mano:
    q:the access time of cache memory is 100 ns and that of main memory
    1000 ns. it is estimated that 80% of the memory requests are for read
    and the remaining 20% for write. the hit ratio for read access only is
    0.9. a write -through procedure is used.
    a- what is the average access time of the system considring only
    memory read cycles?
    b-what is the average access time of the system for both read asn
    write requests?
    c-what is the hit ratio taking into consideration the write cycles?
    please, we are appreciating any response .
