16 days is the correct answer. The snail can go 5 feet each day... and slides back 4 each night. He will get to the 19th foot on the 15th DAY but will slide back to the 15 foot mark on the 15th NIGHT.
He will climb 5 feet on the 16th day, reaching the 20 foot mark.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
