## Homework Statement

## The Attempt at a Solution

I tried to do this problem by taking the average of the y-bar centroid values but that gave me the wrong answer. I am only interesting in knowing why this method is incorrect.

Thanks!

As your grandmother should have taught you, don't take an average of averages. If an elephant and a flea get on opposite ends of a symmetric seesaw, will they balance? So where's their combined centroid?I tried to do this problem by taking the average of the y-bar centroid values but that gave me the wrong answer.
