please solve it asap!!

Question 2) (15 marks) Assume that the memory access time is 3 ns (nanosecond) for a read operation with a hit in the cache, 6 ns for a read operation with a miss in the cache, 4 ns for a write operation with a hit in the cache, and 10 ns for a write operation with a miss in the cache. Execution of sequence instructions involves 80 memory read operations and 60 memory write operations. Given that the cache hit ratio is 0.9, calculate the average memory access time in nanoseconds) in executing the sequence of all instructions
