Usually a report is fetched from the database where data from all previous years is available. Once data is fetched, the raw data is compiled and formulated into appropriate report. The reason that report took longer is that user might have selected a date range from last two years until now which means that entire two years data was fetched from the database, operations were performed onto the raw data and the compiled data was then adjusted as per the report output.

Answer:
The answer is below
Explanation:
a)
If the blocks of a file are not put together, that is for nonadjacent block of files to each other, the time (t) taken to read a 100 block file is:
t = (average seek + rotational latency + transfer time) * 100 block
Average seek = 5 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec
t = (5 + 10 + 0.02) * 100 = 1502 msec
b)
If the blocks of a file are put together, that is for adjacent block of files to each other, the time (t) taken to read a 100 block file is:
t = (seek time * mean interblock distance + rotational latency + transfer time) * 100 block
seek time = 100 microsec = 0.1 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec, mean interblock distance = 2 cylinders
t = (0.1*2 + 10 + 0.02) * 100 = 1022 msec
