Understanding Bathtub Water Drainage

The video tutorial explains a problem involving a student draining water from a bathtub. It uses a graph to illustrate the relationship between time and water volume. Initially, the tub contains 16 liters of water. The tutorial demonstrates how to calculate the rate of water drainage, which is 4 liters per minute, and determines that it takes 4 minutes to completely drain the tub. The video provides a step-by-step approach to solving similar problems using graph analysis.

What does the X-axis represent in the graph related to the bathtub problem?

• The temperature of the water

• The amount of water in liters

How long does it take to completely drain the bathtub?

• 2 minutes

• 3 minutes

• 4 minutes

• 5 minutes

What is the final amount of water in the bathtub when it is fully drained?

• 0 liters

• 2 liters

• 4 liters

• 6 liters

What is the significance of reaching zero liters in the context of the problem?
