Answer:

About 13 hard drives

Explanation:

Using the rule of three, if studying the access speed of 40 hard drives gives the maximum estimate error of 15, then we multiply 5 (which is the number of estimates that are sought in a second attempt) by 40 hard drives divided by 15 as maximum estimate number. We get a total of 13.33,<em> therefore we would need an approximate of 13 hard drives to reduce the maximum estimation error to 5.</em>

  40 hard drives   ---- 15  

13.33 hard drives ---- 5

(40 * 5) / 15 = 13.33 hard drives
