Final answer:
Sarah will use 24 gallons of water in 30 minutes when she turns on the soaker hose in her flower bed.
Step-by-step explanation:
To find the amount of water used in 30 minutes, we need to determine how much water is used in 1 minute and then multiply that by the number of minutes.
Since the soaker hose releases 192 gallons of water every 4 hours, we can find the amount of water released in 1 hour by dividing 192 by 4. This gives us 48 gallons of water per hour.
To find the amount of water released in 1 minute, we divide 48 by 60 (the number of minutes in an hour).
This gives us 0.8 gallons of water per minute.
Finally, to find the amount of water used in 30 minutes, we multiply 0.8 by 30.
So, Sarah will use 24 gallons of water in 30 minutes.
