Saving Time

Our man Ostap was going home from Kiev. He rode halfway by train – fifteen times as fast as he goes on foot. The second half he went by ox team. He can walk twice as fast as that. Would he have saved time if he had gone all the way on foot? If so, by how much?

Answer

Yes. He took as much time for the second half of his trip as the whole trip would have taken on foot.

So no matter how fast the train was, he lost exactly as much time as he spent on the train. He would have saved ¹⁄₃₀ of the time by walking all the way.

Riddle Answer

Puzzle of the Matches

A friend of mine emptied a box of matches on the table and divided them into three heaps, while we stood around him wondering what he was going to do next.

He looked up and said, “Well friends, we have here three uneven heaps. Of course you know that a match box contains altogether 48 matches. This I don’t have to tell you. And I am not going to tell you how many there are in each heap.”

“What do you want us to do?” one of the men shouted.

“Look well, and think. If I take off as many matches from the first heap as there are in the second and add them to the second, and then take as many from the second as there are in the third and add them to the third, and lastly if I take as many from the third as there are in the first and add them to the first—then the heaps will all have equal number of matches.”

As we all stood there puzzled he asked, “Can you tell me how many were there originally in each heap?” Can you?
