Form 2: Water Filling and Draining Rates

Explore how water filling and draining rates represent positive and negative rates of change. Interpret rates from contextual graph scenarios.

Questions

  1. MultiChoice

    A pool is filling up. A graph shows volume (gallons) over time (minutes) passing through (0, 0) and (5, 20). What is the filling rate?

  2. MultiChoice

    A water tank drains from 50 gallons to 0 gallons in 5 minutes. What is the rate of change of water volume?

  3. MultiChoice

    In a graph of water volume vs time, what does a positive slope represent?

  4. MultiChoice

    What does a negative slope in a volume-time graph indicate?

  6. MultiChoice

    If a graph of water volume against time is a horizontal line, what does it mean?

  7. MultiChoice

    Pipe A fills a tank with slope 8 gal/min. Pipe B fills a tank with slope 12 gal/min. Which pipe fills faster?

  8. MultiChoice
