(b) A system has level-1 cache and level- 2 cache. The hit rate for level- 1 cache is 90% and the hit rate of level-2 cache is 80%. An access to level-1 cache requires one cycle, an access to level-2 cache requires four cycles, and an access to main memory requires 50 cycles. What is the average memory access time?
