Question

The dog has gone 5/8 of the way across the yard. How much farther does it have to go to reach the gate?

Answer 1

Well if one assumes that the dog is starting at one side opposite the gate and is heading directly for it, then it has 3/8 of the yard to go. However since one cannot know where the dog has started his movement toward the gate then the answer would not be solvable without more information.
