If an aircraft sprays 20.2 gallons per minute, how long is needed to spray out 147 gallons?

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

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

In this case, you're dividing 147 gallons by the spraying rate of 20.2 gallons per minute:

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

When rounded, this means it takes approximately 7.3 minutes to spray out 147 gallons. This calculation shows that the time required matches the rate of spraying and accurately reflects the relationship between the volume of liquid and the spraying rate.
