Salut @Nébulette !

 

Il faut utiliser la formule Vmoy=Débit/Section

 

Si on te donne seulement le rayon alors tu remplaces la surface par pi.r², ici on te donne directement la section qui est de 1cm².

 

Il faut aussi penser à convertir le débit en cm³/min ce qui te donne 1L/min=1000 cm³/min

 

Ainsi, Vmoy=1000/1=1000cm/min=10m/min

 

Je sais pas si tout ces calculs sont clairs.
