If an aircraft sprays 20.2 gallons per minute, how long would it take to spray out 147 gallons of mixture?

To determine how long it takes to spray out 147 gallons at a rate of 20.2 gallons per minute, you would divide the total volume of mixture by the rate of spray.

The calculation is as follows:

Time (in minutes) = Total gallons / Gallons per minute

= 147 gallons / 20.2 gallons per minute

≈ 7.27 minutes.

When rounded to one decimal place, this value is approximately 7.3 minutes, which corresponds to the selected answer. This reflects the necessary calculations based on the flow rate and the volume sprayed, demonstrating how efficient aerial applicators can manage the mixture application in farming practices effectively.

Understanding this concept is crucial for effective time management and resource allocation in aerial applications, ensuring that operators can accurately gauge the duration required for spraying tasks based on their aircraft's capacity.
