Answer:
The six-row combin harvests 285 bushels of corn per hour.
Explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, you can apply the following formula:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{a*b}{c}[/tex]
In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?
[tex]x=\frac{266 pounds*1 bushel}{56 pounds}[/tex]
x=4.75
This is, a six row combin harvests 4.75 bushels of corn per min.
So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?
[tex]bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}[/tex]
bushels of corn= 285
The six-row combin harvests 285 bushels of corn per hour.
