If you walk faster vs slower, will you apply more or less chemical per unit area?

• A. More
• B. Less
• C. About the same
• D. The rate cannot be determined

Answer: (B)

When you spray with a constant output and you walk faster, you cover more ground in the same amount of time, so the chemical is distributed over a larger area. That means you apply less chemical per square unit of area. If you slow down, you spend more time over each patch, so more chemical ends up per unit area. To hit a target rate, you’d need to adjust either your speed or the spray output (change nozzle, pressure, or flow) so the amount applied per area matches the label recommendation. For example, with a fixed spray rate, doubling your speed reduces the amount per area, while halving your speed increases it.
