The perimeter of the rectangular base of a tank is 400 cm. The ratio of its length to its breadth is 3 : 2. When 48 ℓ of water are poured into the tank, 25 of it is filled. Find the height of the tank.
Level 3
A pool measuring 50 m x 25 m x 2 m was completely filled with water. The water was draining out of the tank at a constant rate and became completely empty after 25 minutes.
What fraction of the pool was filled with water at the end of 24 minutes? Express the answer in the simplest form.
How many litres of water was drained out of the pool at the end of 10 minutes?
