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

To determine how long it takes for an aircraft to spray out 147 gallons at a rate of 20.2 gallons per minute, you need to perform a straightforward calculation by dividing the total volume of liquid to be sprayed by the spray rate.

The formula used in this scenario is:

Time (minutes) = Total gallons to spray / Spray rate (gallons per minute)

Substituting the provided numbers:

Time = 147 gallons / 20.2 gallons per minute

When you conduct this division, you find that it results in approximately 7.27 minutes. This value aligns closely with the answer stated as C, which represents 7.3 minutes when rounded to one decimal place.

This calculation demonstrates the relationship between the flow rate and the total amount to be sprayed, emphasizing the importance of understanding spray rates and how to apply them in context to achieve the desired application efficiently.
