Answer 1

$1h \to 60 min \\ 1min\to 60 s \\\\ 1h\to 60*60=3600 s \\\\\\ 2min45s= 2*60+45= 120+45= 165 s \\\\ 24h \to 24*60min=1440min \to 60*1440s = 86400 s \\\\\\ 165s...........20l \\\\ 86400s........x \\\\\\ x=\frac{86400s*20l}{165s} \\\\ x= \frac {17280*20l}{33} \\\\ x=\frac{345600l}{33} \\\\ \boxed{x=10472,72l}$
