Answer:
0.83 m³/s Â
Explanation:
The speed of the airflow is given as;
       1.85 x 10³ ft³/min
Now we are to express this unit in m³/s Â
  1ft  = 0.3m
  60s  = 1 min
So;
 1.85 x 10³  x ft³ x [tex]\frac{1}{min}[/tex] x [tex]\frac{(0.3m)^{3} }{ft^{3} }[/tex] x [tex]\frac{1min}{60s}[/tex] Â
  = 0.83 m³/s Â
