Extracted text: The memory access time is I nanosecond for read operation with a hit in cache. * nanoseconds for a read operation with a miss in cache, 2 nanoseconds for a write operation with a hit in cache and 10 anoseconds for a write operation with a miss in cache. Execution of a sequence of instructions involves 100 instruction fetch operations, 60 memory operand read operations and 40 memory operand write operations. The cache hit-ratio is 0.9. The average memory access time (in nanoseconds) in executing the sequence of instructions is
