The problem of a government executive and an official machine that can only be solved by exceptional smart people.
We often hear parents complain about overly difficult school math problems. But in fact, only a very few of them manage to baffle holders of higher education diplomas. Today you are facing one of such intricate problems from a Soviet textbook. Can you solve it? This is a great way to check whether the brain is still rusty, faced day by day with simple and similar tasks.
For a minister living in a country outside the city, at the same time in the morning comes a service car. One day a man decided to walk. He got out 1 hour before the car arrived and went to meet her.
On the way, the minister met the car, got into it, and the driver brought him to work 20 minutes earlier than usual. Question: How long did the walk last?
We believe that the speed of the car is always constant, it turns instantly and comes always at the same time.
A typical school problem, which is easy to solve in your mind, no equations and formulas are not needed here. That's just without logic and ingenuity can not do, because for some reason it seems that the data for the solution is clearly not enough.
The first motivation is to find the speed of the machine and then act according to the usual pattern. But the problem, the distances are not specified. Well, let's get this straight. If the minister hadn't gone to meet the car, she would have had to drive there and back longer. And this time is equal: how much the car went from the meeting place to the cottage, so much and back.
The total travel time was reduced by 20 minutes. So the car was 10 minutes shorter and 10 minutes shorter back. It turns out that the meeting between the driver and the boss occurred 10 minutes earlier than the appointed time. The Minister left 60 minutes before the scheduled time. So, on the way, our walker spent 50 minutes!
However, an attentive reader will find in the problem a discrepancy. It turns out that in 50 minutes, the pedestrian walked the distance that the car covered in 10. If we assume that the speed of the limousine was (take at least) 60 km / h, then the man walked at a speed ... 12(!) km/h
Either the minister turned out to be extremely fast, or the government machine is barely breathing. But this is, as they say, nitpicking. And the problem is good because, with apparent complexity, it is easy to solve if you connect logic and properly scour your brain.
