seek time = 4ms/track

search time= 1.7ms/sector

2,5   1*4=4              5*1.7= 8.5        4+8.5+0.5 = 13

1,2   1*4=4              2*1.7=3.4         4+ 3.4+0.5  =7.9

1,0   0                      0                   0+0+0.5=0.5

2,3    1*4=4            3*1.7= 5.1        4+ 5.1+0.5=9.6

2,4     0                 4*1.7= 6.8        0+6.8+0.5=7.3

1,0     1*4=4                 0               4+0+0.5=4.5  

Total time= 13+7.9+0.5+ 9.6+7.3+4.5=42.8 ms

Remember Data transfer is 0.5 for all.

Explanation:

The mean time it takes from one track to another is seek time. hence = track difference * seek time per track

And similarly search time = no. of sectors * search time per sector

And this we have used to calculate above.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
