Question

4.
There are 40 litres of water in a barrel.
The water flows out of the barrel at a rate of 125 millilitres per second.
1 litre = 1000 millilitres.
Work out the time it takes for the barrel to empty completely.

Answer 1

40 liters = 40000 ml

40000/125 = 320

It would take 320 seconds or 5 minutes 20 seconds.

Hope this helps! Any questions let me know :)
