Can You Understand The Logic Question That Confused Even Einstein?

Although we don’t really enjoy solving at school desks, actually. some math questions Solving is so much fun. In particular, the solution phase of questions that will enter logic and encourage you to think can be both educational and entertaining.

Now we are here with one more of these questions. Moreover, the question we will ask today is from the most famous scientists in the world. Albert EinsteinIt’s a question that has confused even him. Asked in a letter by Einstein’s close friend Max Wertheimer, famous physicist It was difficult at first, causing him to think wrong until he understood the subject. So let’s take a closer look at this question.

Question involving 1 hill and an old car going up that hill:

You want to drive home using an old car. But there is a hill in front of your path. You have to travel 1 km to go up this hill and 1 km to descend. Because the car is old It can go up to 15 km/h. During the descent, it can go faster. The question is as follows: At what speed must the car go downhill so that the speed of the car is 30 km/h on average for a 2-kilometer journey?

Let’s give you some time to think about the answer.

Are you one of those who find the answer 45? Unfortunately this is not the answer.

It was a question that challenged even a physicist like Einstein.

Let’s be realistic, Even if it seems very logical to find the answer 45 And if this was the answer, we would expect Einstein to do this directly from the head. When this question was asked, Einstein, a scientist who won the Nobel Prize in Physics, took a pen and paper and tried to solve this question. Later, he confessed to his friend that he thought wrong at first. In that case Confusing even Einstein Let’s take a closer look at the answer to this question.

What is the answer to the question? (Or we could say there is.)

Since most of us add 15 and 45 and then divide 60 by 2, we get 30, so we gave 45 as the answer. But before you do that, on a 2 kilometer trip, the car’s It is necessary to calculate the time required for it to travel at 30 km.

After all, our car It will spend a certain time for the 2 kilometer road. We can calculate this as 2/30, ie 1/15. When we divide this by 1 hour, we get 4 minutes from 60/15. In other words, when the car travels at an average speed of 30 km/h, it has to cover the 2-kilometer road in 4 minutes.

This is where things start to get complicated.

We saw that the car can travel a distance of 2 km with an average of 30 km/h in 4 minutes. The main information given to us is It was to go a distance of 1 km at a speed of 15 km. For this, we need to make a calculation similar to the one above.

When we divide 1/15 by 1 hour, we see it again. We see that there is a time of 4 minutes. So this old slow car can cover 1 km at 15 km/h in 4 minutes. Therefore, there is actually no answer to the question. Because there is an error in the question. After all, there is not enough time to go down the hill.

So how did you come up with this logically flawed question? “Did you notice there was a problem?” from the very beginning, or are you one of those who find 45 at first like us? Let’s meet in the comments.
