Answer 1

To convert the dripping rate from milliliters per minute to liters per hour, we can use the following conversions:

1. There are 1,000 milliliters in a liter.
2. There are 60 minutes in an hour.

The dripping rate is 12 milliliters per minute.

First, convert the rate to liters per minute:

\[
\text{Liters per minute} = \frac{12 \text{ milliliters}}{1000} = 0.012 \text{ liters per minute}
\]

Next, convert liters per minute to liters per hour:

\[
\text{Liters per hour} = 0.012 \text{ liters per minute} \times 60 \text{ minutes per hour} = 0.72 \text{ liters per hour}
\]

Therefore, the dripping rate of the faucet is approximately **0.72 liters per hour**.

The correct response from the options provided is:

**0.72 liter per hour**.
