Answer:
Total time = 190 ms
Explanation:
The requests missing in question are:
Requests ( A, 80) , (B,75) , (C,82) , (D,90) , (E,45)
Number of movements = | 70 - 45 | + | 45 - 0 | + | 0 - 75 | + | 75 - 80 | + | 80 - 82 | + | 82 - 90 |
= 35 + 45 + 75 + 5 + 2 + 8
= 70 + 80 + 10
= 160
Time taken for seek = 160 * 1 ms = 160 ms
Time taken for servicing request = Number of tracks * Time for each track = 5*6 = 30
Total time = 160 + 30 = 190 ms.
