This month question is:A gelert farmer ploughing his field walks 100 metres in a certain direction. He stops for a while, ponders, and then walks another 50 metres. He then stops, looks up in the air, looks down and walks 50 metres. The gelert farmer then turns 90 degrees and walks another 100 metres. He puts his hand to his chin, and scratches it for a while, then turns another 90 degrees and walks 100 metres. The farmer then drops some seeds on the ground, rotates 90 degrees and walks 50 metres.
Suddenly, the farmer realises that he has forgotten something. He turns towards his starting point, walks thirty metres, and then stops.
During his journey, what was the farthest distance he could have been away from his starting point?
