Consider a disk system having $60$ cylinders. Disk requests are received for cylinders $10,22,20,2,40,6,38$ in that order. Assuming the disk head is currently at cylinder $20$, what is the time taken to satisfy all the requests if it takes $2$ milliseconds to move from one cylinder to adjacent one and SSTF algorithm is used?
