Thank you for the opportunity to help you with your question!

The average speed is inversely proportional to the square root of the molar mass.

molar mas of oxygen=32

molar mass of CO2= 12+2*16=44

v(CO2)/v(02)= (m(O2)/m(Co2))^0.7

=(32^O.7)/(44^0.7)=0.8

v(CO2)=0.8*443=354.4m/s

Please let me know if you need any clarification. I'm always happy to answer your questions.
