What is the number of acres treated per minute when the aircraft is traveling at 130 MPH with an effective swath width of 65 feet?

To determine the number of acres treated per minute, we first need to convert the speed of the aircraft from miles per hour to feet per minute. Since there are 5280 feet in a mile, an aircraft traveling at 130 miles per hour is moving at:

130 miles/hour * 5280 feet/mile = 686400 feet/hour.

Next, to find the feet covered per minute, we divide by 60:

686400 feet/hour ÷ 60 minutes/hour = 11440 feet/minute.

Now, we can calculate the area covered in one minute by multiplying the speed (in feet per minute) by the effective swath width (in feet). The swath width is given as 65 feet:

Area covered per minute = 11440 feet/minute * 65 feet = 743600 square feet/minute.

To convert square feet to acres, we note that there are 43,560 square feet in one acre:

743600 square feet/minute ÷ 43560 square feet/acre ≈ 17.1 acres/minute.

The calculations confirm that the correct answer is approximately 17.1 acres treated per minute when the aircraft is operating at 130 MPH with a swath width of
