Well they give you the equation and they want you to solve for time given that you know the amount of water in the tank. They tell you T=274 and that

T=450-8m so using the value T=274 in the equation to the left gives you:

274=450-8m subtract 450 from both sides

-176=-8m divide both sides by -8

22=m

So 22 minutes have passed when there is 274L remaining...
