For this case we propose a rule of three taking into account that:
1 hour equals 60 minutes, then[tex]\frac {1} {2}[/tex] hour equals 30 minutes.
272 chairs --------------> 8 hours
x ----------------------------> [tex]\frac {1} {2} hour[/tex]
Where "x" represents the amount of chairs produced in 30 minutes.
[tex]x = \frac {\frac {1} {2} * 272} {8}\\x = \frac {136} {8}\\x = 17[/tex]
Thus, in half an hour 17 chairs are produced.
Answer:
In half an hour 17 chairs are produced.
