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

To determine how long it will take to spray 147 gallons of a mixture when the aircraft sprays at a rate of 20.2 gallons per minute, you can use the formula:

Time = Total Volume / Flow Rate.

Inserting the given values into this formula, you calculate the time as follows:

Time = 147 gallons / 20.2 gallons per minute = approximately 7.27 minutes.

When rounded to one decimal place, this time equals about 7.3 minutes. This is aligned with the calculations that lead to the chosen answer, demonstrating the proper application of the formula for flow rates in aerial application scenarios. This process highlights the importance of accurately using flow rates to make timely and efficient agricultural applications in aerial operations.
