What is the per acre application rate of a centrifugal granular spreader that traveled 430 feet and applied 16 lbs of material?

To determine the per acre application rate of a centrifugal granular spreader, you need to convert the distance traveled and the amount of material applied into an application rate per acre.

First, understand that there are 43,560 square feet in one acre. The centrifugal granular spreader traveled 430 feet while applying 16 lbs of material. To find the application rate per acre, calculate how many times the spreader would need to travel the 430 feet to cover an entire acre.

1. Calculate how many 430-foot segments fit into one acre:

[

\frac{43,560, \text{feet}}{430, \text{feet}} \approx 101.3

]

2. Now, since the spreader applied 16 lbs in that 430-foot distance, you multiply the amount of material applied by how many 430-foot segments fit into an acre:

[

16, \text{lbs} \times 101.3 \approx 1,620.8, \text{lbs}

]

3. Finally, calculate the application rate per acre:

[

\frac{1,620.8, \text{lbs}}{1, \
