Final answer:
You would need to drink from your water bottle 2 times (b=2) to consume 2 liters of water.
Step-by-step explanation:
To find out how many times you need to drink from your water bottle (b) to consume 2 liters of water (l), we need to consider the volume of the water bottle. In Figure 3.4.2, a typical water bottle is shown to have a volume of 1 liter. Therefore, if you want to drink 2 liters of water, you would need to drink from your water bottle 2 times (b=2).
