Question

A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) Round to the nearest Whole Number.

Answer 1

The six-row combin harvests 285 bushels of corn per hour.

Step-by-step 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:
`x=(a*b)/(c)`

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?

`x=(266 pounds*1 bushel)/(56 pounds)`

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?

`bushels of corn=(60 minutes*4.75 bushels of corn)/(1minute)`

bushels of corn= 285

The six-row combin harvests 285 bushels of corn per hour.
