The seek time can differ for a given disc due to the varying distance from the start point to where the read/write head has been instructed to go. Because of these variables, seek time is generally measured as an average seek time. Let's come to a moment when the disk drive is reading from cylinder 20, disk requests for cylinders 10, 22, 20, 2, 40, 6, and 38 arrive at the disk driver. The seek time each cylinder is 6 milliseconds. If the disk arm scheduling methods are first- come-first-served, the overall seek time is?
