Final answer:

To determine the time it takes for the water level to drop, calculate the initial volume, establish the rate of water loss, and solve the equation to find the time.


Explanation:

To find the time it takes for the water level to fall by 20 cm:

  1. First, calculate the volume of water in the tank initially.
  2. Then, determine the rate of water loss per hour and set up an equation to find the time taken for the water level to drop by 20 cm.
  3. Solve the equation to find the time it will take for the water level to decrease by 20 cm.
