Can anyone help me out with this excercise?

Consider a single-platter disk with the following parameters: rotation speed: 5400 rpm; number of tracks on one side of platter: 10,000; number of sectors per track: 600; seek time: one ms for every hundred tracks traversed. Let the disk receive a request to access a random sector on a random track and assume the disk head starts at track 0.

a. What is the average seek time?

b. What is the average rotational latency?

c. What is the transfer time for a sector?
