Need Help solving this please and thank, show all work for solution

Question 2 [Points 5] Consider a system running 1 CPU-bound task (C1) and 1I/O bound tasks (I1). I/O bound task issues an I/O operation (of 20 milliseconds duration) for every 2 milliseconds of CPU time. CPU-bound task issues an I/O operation (of 1 millisecond duration) for every 15 milliseconds of CPU time. A CPU-bound task requires 30 milliseconds of CPU to complete and an I/O-bound task requires 6 milliseconds of CPU time. - Assume that there is only one I/O device (so multiple I/O requests may have to queue). - Assume that CPU context switch time is negligible. - Assume that the ready queue has C1, I1 jobs in that order with C1 at the front of the queue. There are no jobs in the system at time 0 . - Assume FCFS scheduling for both CPU and I/O. - For any job, an execution cycle has CPU execution followed by I/O. Show through Gantt charts (as a table) how the I/O and CPU are allocated and compute the average turnaround times for the CPU-bound and I/O-bound tasks. (Note: Each CPUbound job ends with an I/O operation which is unusual. But that is okay for this example.)
