With an application rate of 11.3 gallons per acre, how many acres can be covered with 147 gallons of spray mixture?

To determine how many acres can be covered with 147 gallons of spray mixture at an application rate of 11.3 gallons per acre, the calculation involves dividing the total gallons available by the application rate.

First, divide the total amount of spray mixture (147 gallons) by the application rate (11.3 gallons per acre):

147 gallons ÷ 11.3 gallons per acre = 13 acres.

This calculation shows that with 147 gallons of spray mixture, one can treat exactly 13 acres at the specified application rate. Thus, the correct answer indicates that 13 acres can be effectively covered with the given amount of spray mixture, confirming the effectiveness of the calculation in relation to agricultural practices for aerial application.
