Walking

Atraveller walking along a road asked an old man working in a field to
how long it would take to get to the next village. But the old man didn.t
answer, so the traveller kept walking.

He hadn´t gone far when he heard a call: "Hi, mister, it´ll take you about 20
minutes".

"Why didn.t you tell me that when I asked you?"asked the traveller.

"How did I know how fast you were going to walk?" replied the old man.
