198 ml of saline have been administered already.

To calculate the amount of saline administered, we need to consider the following information:

Total volume: 1200 ml

Rate: 2 hourly, meaning 1200 ml is administered in 2 hours.

Time elapsed: 20 minutes

Step 1: Convert minutes to hours

First, we need to convert the time elapsed from minutes to hours:

20 minutes / 60 minutes/hour = 0.33 hours

Step 2: Calculate the amount of saline administered per hour

Divide the total volume by the rate per hour:

1200 ml / 2 hours = 600 ml/hour

Step 3: Calculate the amount of saline administered over 20 minutes

Multiply the hourly rate by the time elapsed:

600 ml/hour * 0.33 hours = 198 ml

Therefore, 198 ml of saline have been administered already.
