There is a chain nailed to the wall. The chain is 10 feet long and the center of the chain dips down 5 feet from where each side of the chain is nailed to the wall. How far are the 2 ends of the chain from each other?
if we multiply both sides by 3 we get
The answer is...drumroll... 0, nada. "Why?" you may ask. Btw, I found this on the internet. It has to be 0 because it dips 5 feet down, and 5 feet upwards. So it's 0. Ta-da!
