How can you determine the number of Acres covered by one spray tank?

• A. Divide tank capacity by gallons per acre (application rate)
• B. Multiply tank capacity by gallons per acre
• C. Add tank capacity to gallons per acre
• D. Subtract gallons per acre from tank capacity

Answer: (A)

You determine how many acres a spray tank will cover by relating the tank’s volume to the application rate. The key idea is that the number of acres equals the tank capacity (in gallons) divided by the gallons per acre you plan to apply. This works because gallons per acre tells you how many gallons are needed to treat one acre, so dividing the total gallons you have by that per-acre amount yields the total acres that can be treated.

For example, a 100-gallon tank at 10 gallons per acre covers about 10 acres (100 ÷ 10 = 10). If you have 50 gallons at 2 gallons per acre, you’d cover 25 acres.

Multiplying the tank capacity by gallons per acre would mix incompatible units and not represent area. Adding or subtracting the two quantities likewise doesn’t reflect how many acres can be treated based on a total volume and per-acre rate.
