Answer:
Cheryl drinks 28000 milliliters of water in 7 days.
Cheryl must drink water for 20 days to meet her minimum requirement of 80000 milliliters of water.
Explanation:
Step 1: Convert 4 liters to milliliters:
Since we want our first answer to be in milliliters, we can go ahead and convert 4 liters to milliliters using 1000 mL / 1 L as a conversion factor:
4 L * (1000 mL / 1 L)
4000 mL
Thus, Cheryl must drink 4000 mL of water a day.
Step 2: Determine how much water Chery drank in 7 days:
We know that the total amount of water Cheryl drinks equals the product of time in days and daily water consumption in milliliters:
Total amount = time (days) * daily water consumption (milliliters)
Thus, we can determine how much water she drank in 7 days by multiplying 7 by 4000:
Total amount = 7 * 4000
Total amount = 28000
Therefore, Cheryl drank 28000 milliliters of water in 7 days.
Step 2: Determine how many days must Cheryl drank water to meet her minimum requirement:
- We know that the total amount of water equals the product of time and daily water consumption and that Cheryl drinks 4000 milliliters of water a day.
Thus, we can determine how many days Cheryl must drank water to meet her 80000 milliliter requirement by dividing 80000 by 4000:
Total amount / daily water consumption = time
80000 / 4000 = time
20 = time
Therefore, it will take Cheryl 20 days to drink 80000 milliliters of water, given that she drinks 4000 milliliters of water daily.
