Assume that the tank fills in x minutes

By Direct Proportion,

x1/y1 = x2/y2

220/1 = 45000/x

x = 45000/220

x = 204.54 

x = 205 minutes (approx.)

Divide x by 60 in order to convert from Minutes to Hours

⇒ 205/60 = 3.41 hours

Estimating to nearest half hours, 

The 45000 L tank is filled in 3.5 hours at the rate of 220 L/m
