Question

a water pail in your backyard has a small hole in it. you notice that it has drained a total of 2.5 liters in 4 days. what is the average change in water volume each day?
the average change in water volume is (\boxed{}) liter(s) per day.

Explanation:

Step1: Identify the formula for average rate

The average change in volume per day is total volume drained divided by number of days, so we use the formula $\text{Average Change} = \frac{\text{Total Volume Drained}}{\text{Number of Days}}$.

Step2: Substitute the values

Here, total volume drained is $2.5$ liters and number of days is $4$. So we calculate $\frac{2.5}{4}$.

Step3: Perform the division

$2.5 \div 4 = 0.625$.

Answer:

$0.625$
