If, at a particular temperature, the average speed of CH4 molecules is 1000 mine/hr, what would be the average speed of CO2 molecules at the same temperature?

what is mine/hr ?

mass* 108.23.118.127averagespeed^2 is proportional to temp

mass CH4=16
mass CO2=44

avgspeedCO2=1000mine/hr * sqrt (16/44)

Sorry I meant mi/hr
