How many minutes are required to spray 147 gallons if the aircraft sprays at 20.2 gallons per minute?

To determine how many minutes are needed to spray 147 gallons at a rate of 20.2 gallons per minute, you can use the formula for time, which is:

Time = Total volume / Rate of spraying.

In this case, you would divide 147 gallons by the rate of spraying, which is 20.2 gallons per minute:

Time = 147 gallons / 20.2 gallons per minute.

Performing the calculation:

147 ÷ 20.2 = 7.27077...

When rounded to one decimal place, this results in approximately 7.3 minutes.

Therefore, the correct answer is supported by the calculation showing how the spraying rate impacts the total time required to cover the volume of 147 gallons, leading to a conclusion that aligns with the precision needed in aerial application activities. Understanding this rate and its implications on time management in spraying operations is essential for effective aerial application practices.
