Problem 12.7. A sequential file is stored in a disk occupying

Problem 12.7. A sequential file is stored in a disk occupying 100 contiguous disk blocks. The disk has an average rotational delay of 2.5 ms. The time taken to seek the head of the drive to the required cylinder is 25 ms and the time taken to read a block is 0.25 ms. Find the minimum, maximum, and average time to search for a record using a linear search process
