How does the actual application rate of pesticide compare to the intended rate when a pilot has 40 gallons remaining after completing 3/4 of a 25-acre field at a rate of 5 gpa?

To determine how the actual application rate of pesticide compares to the intended rate, we start by evaluating the situation presented in the question. The pilot intends to apply pesticide at a rate of 5 gallons per acre (gpa) over a 25-acre field, which suggests that for the entire field, the intended total amount of pesticide is:

25 acres x 5 gpa = 125 gallons.

Since the pilot has already completed 3/4 of the field, we can calculate how much pesticide was intended for that area:

(3/4) x 25 acres = 18.75 acres.

Now we can find the volume of pesticide that should have been applied to these 18.75 acres:

18.75 acres x 5 gpa = 93.75 gallons.

The pilot has 40 gallons remaining after this application, meaning they have applied:

93.75 gallons - 40 gallons = 53.75 gallons.

Next, we assess how much pesticide was actually used over the 18.75 acres:

53.75 gallons applied / 18.75 acres = 2.87 gpa (approximately).

This actual application rate of approximately 2.87 gpa is significantly lower than the intended rate of
