I was talking to Mrs Ruff about my Go Dog! puzzle and she said that it was too confusing (this from a person with multiple degrees but it is much more likely to be me). She said. and you will like this, “Just post an easier puzzle with one tree and be liked”.
My aim is to post a good puzzle that takes some time to solve, her aim is for me to be well liked!
Anyway, here is a puzzle with only 1 tree.
There is one tree, a Birch (
. A squirrel ® looks for nuts around B. While the squirrel is on the ground, it can be caught by a dog (D). The squirrel runs at 3m/s while the dog runs at 4m/s. Given that the dog is 20m from the tree, find the limit that the squirrel can move away from the tree and remain safe (ie not caught by the dog).
