Computer structure question

please as brief as you can, as fast as you can

Consider a disk that rotates at 3600rpm. The seek time to move the head between adjacent tracks is 2ms. There are 64 sectors per track, which are stored in linear order from sector 0 through sector 63. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8 . There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. A) How long will it take to transfer sector 1 on track 8 to sector 1 one track 9. B) How long will it take to transfer all the sectors of track 8 to the corresponding sectors of track 9 ? (10 points)
