For this case we propose a rule of three taking into account that:

1 hour equals 60 minutes, then
\frac {1} {2} hour equals 30 minutes.

272 chairs --------------> 8 hours

x ---------------------------->
\frac {1} {2} hour

Where "x" represents the amount of chairs produced in 30 minutes.


x = \frac {\frac {1} {2} * 272} {8}\\x = \frac {136} {8}\\x = 17

Thus, in half an hour 17 chairs are produced.

Answer:

In half an hour 17 chairs are produced.
