Apainting measures 2.4 feet from left to right. it’s hung in the center of a rectangular wall measuring 20 feet from left to right. what is the distance between the right edge of the painting and the right edge of the wall? assume that the painting does not tilt.

Since the painting is hung in center of a rectangular wall ,the distance between them on either side will be the same.so we can divide the length of the painting and wall by 2.we will get  2.4/2=1.2 feet and 20/2=10 feet .10-1.2=8.8 feet gives the distance between the right edge of the painting and right edge of the wall

The slope best fit isc. 1/6 mile per hour
