How much total herbicide product is needed for a 3-hour exposure at a rate of 3 quarts per hour?

To determine the total amount of herbicide product needed for a 3-hour exposure at a rate of 3 quarts per hour, you simply multiply the hourly rate by the number of hours of application.

In this case, you would calculate:

3 quarts/hour × 3 hours = 9 quarts.

This calculation shows that a total of 9 quarts is necessary for continuous application over the specified time frame. This reflects the total herbicide product required to maintain effective control of aquatic weeds during the entire 3-hour period. By understanding this calculation, you can apply the same method to any future situations where you need to determine total quantities based on rate and time.
