A computer system has the following parameters:

- Cache access time of 25ns

- Memory access time of 44 ns

- Write I/O Miss rate of 20%

- Read I/O Hit rate is 100%

- Disk rotating at 5000 revolutions per second with an average seek time of around 4 microseconds and an average of 200 sectors per track

- As always, you can assume that there are 1024 bytes per sector

If there are a total of 1020 instructions in a program equally split up between read and write I/O operations in this set of instructions, and assuming that there is no required data in main memory, calculate the total time taken for this program to execute in this system.
