The car traveled 20 km, moving north, then he had to turn east and walk another 30 km, after which he turned north again and reached the final destination, having walked another 10 km. Find the path and module of movement of this car.
We will solve this problem using a root.
So, let’s start solving the problem.
We know that the entire path of a car consists of 3 sections of the path.
In formulaic form, this is written as follows:
S = l1 + l2 + l3.
If you substitute the values, it turns out:
S = 20 + 30 + 10.
And it turns out that all the way = 60 kilometers.
And further, using the Pythagorean theorem, we will consistently reach the record:
L = √302 + (20 + 10) ^ 2.
And, after we calculate all this, it will come out that L = 51.9 meters.
That is, almost 52 meters.
