What was the volume of water (Liters) in the tank at the begining (t = 0)?

If that is 1/5 volume of the tank - how much water can the tank hold when it is filled?

Nevertheless, you will be asked inept questions all your life so do your best to answer the question by estimating what the graph says the relevant numbers are and writing them down so you can think. At that point, this becomes just an arithmetic problem. (It can also be treated as a very simple algebra problem, but I am guessing that you have not learned any algebra yet.)

For (b), looking at the graph, 50L of water was lost every 5 minutes, so calculate that to 10L per minute.

There was 225L in the tank so it would take 22.5minutes for all the water to flow out. Or 22 minutes and 30 seconds

If you look at the graph, it shows at 0 minutes there was 75L of water.What was the volume of water (Liters) in the tank at the begining (t = 0)?

Looks good to me.

Thanks

Looks good to me.

(Notice, out of interest, 75 litres at the start is [MATH]\dfrac{1}{5}[/MATH], so [MATH]3 \times 75[/MATH] litres = 225 litres is [MATH]\dfrac{3}{5}[/MATH]).
