Question

I have a friend that flys a crop duster(sprayer)---when spraying he is flying 150 mph and spraying a swath 70 foot wide-----how many acres does he spray a minute?

Answer 1

This is my answer, but I want you folks to check me and see if I am correct---
150 mph x5280==792000 ft x70 ft swath===55,440,000 sq. ft divide by 43,560 sq ft (amount in an acre) ===1272 acres per hour----divide by 60 ===21.21 acres per second------some one tell me if I am correct---Howard (83 yrs old)
