How many gallons are sprayed per mile when an aircraft has a spray output of 8 gallons per minute and travels at 130 miles per hour?

To determine how many gallons are sprayed per mile, we first need to calculate the aircraft's speed in terms of gallons per minute and convert that to a per-mile basis.

The aircraft is traveling at 130 miles per hour, which can be converted to miles per minute. There are 60 minutes in an hour, so:

130 miles per hour ÷ 60 minutes per hour = approximately 2.17 miles per minute.

Next, we know the aircraft has a spray output of 8 gallons per minute. To find out how many gallons are sprayed per mile, we divide the gallons sprayed in one minute by the miles traveled in that same minute:

8 gallons per minute ÷ 2.17 miles per minute ≈ 3.69 gallons per mile.

Rounding to one decimal place leads us to approximately 3.7 gallons per mile. This shows that when flying at 130 miles per hour with a spray output of 8 gallons per minute, the aircraft will spray about 3.7 gallons of liquid for each mile flown. This calculation underlines the relationship between speed and output in aerial application scenarios.
