To calculate the Acres Per Hour (APH):
\[ APH = \left( \frac{MW}{12} \right) \times \left( MS \times 5280 \right) / 43560 \times 0.90 \]
Where:
Acres per hour is a unit of square area per unit of time, in this case, acres and hours respectively. The term is most often used in landscaping to describe how much area a lawnmower can cut per hour.
Let's assume the following values:
Using the formula:
\[ APH = \left( \frac{60}{12} \right) \times \left( 5 \times 5280 \right) / 43560 \times 0.90 = 5 \times 26400 / 43560 \times 0.90 \approx 2.73 \text{ acres/hour} \]
The Acres Per Hour is approximately 2.73 acres/hour.
