5.Consider a single-platter disk with the following parameters:
- Rotation speed: 7200 rpm;
- Number of tracks on one side of platter: 30,000
- Number of sectors per track: 600;
- Seek time: one ms for every hundred tracks traversed.
- Assumption: Let the disk receive a request to access a random sector on a random track and assume the disk head starts at track 0.
What is the average seek time?
