Answer: 10 seconds

Explanation:

m here means mean.

Mean or more accurately arithmetic mean, is calculated by adding all the terms and then dividing by the number of terms.

If there are 5 terms being 4, 5, 5, 6 and a fifth one which is x, and the mean is 6. The relevant expression is:

(4 + 5 + 5 + 6 + x) / 5 = 6

Solving it:

4 + 5 + 5 + 6 + x = 6 * 5

20 + x = 30

x = 30 - 20

x = 10 seconds

Explanation:

Practical intelligence uses everyday knowledge for everyday tasks. Through process of elimination, we can get rid of 'Conducting careful analysis to solve a problem' and 'Breaking a problem into parts to solve.' And not giving up has nothing to do with intelligence, thats preseverance.
