Answer 1

5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)

Explanation:

Let's find out how much each tractor can plow each hour.

`(600^(2) )/(3*2)=60,000m^(2)` per tractor per hour

`1,000^(2)=1,000,000m^(2)` is the area of the field of side length 1,000 meters

5 tractors can plow
`300,000m^(2)` per hour.

`(1,000,000)/(300,000)=3.33` hours
