34% of an hour(3600 seconds) is 34/100 * 3600 = 34 * 36 = 35*35 - 1 = 1224 seconds.

Since we have 9 minutes and 50 seconds, which is 9*60 + 50 = 590 seconds
The remainder is 634 seconds(which is 10 minutes and 34 seconds) which must be added.

Therefore, x equal 10 minutes, 34 seconds(Option C)

P.S When the answer options are far apart, approximations may work, but with close
answer options it makes sense to convert the time into seconds.
_________________

You've got what it takes, but it will take everything you've got

\(9*60 + 50 + x = \frac{34}{100}*60*60\)

\(590 + x = 1224\)

So, \(x = 634\)

Answer will be (C) 10 minutes, 34 seconds
