Problem Analysis

We are given the following information: - A pedestrian walks from a dacha settlement to a train station. - After 50 minutes, a cyclist leaves the same dacha settlement and catches up with the pedestrian 20 minutes later. - The pedestrian covers 5 km more than the cyclist in 3 hours, while the cyclist covers the same distance in 30 minutes.

We need to find the speed of each person.

Solution

Let's assume the speed of the pedestrian is P km/h and the speed of the cyclist is C km/h.

We know that the pedestrian covers 5 km more than the cyclist in 3 hours. This can be expressed as:

3P = 5 + 3C We also know that the cyclist covers the same distance as the pedestrian in 30 minutes. This can be expressed as:

0.5C = P We have a system of two equations with two variables. We can solve this system to find the values of P and C.

Let's solve the system of equations:

From equation we can express P in terms of C:

P = 0.5C [[3]]

Substituting equation [[3]] into equation we get:

3(0.5C) = 5 + 3C

Simplifying the equation:

1.5C = 5 + 3C

1.5C - 3C = 5

-1.5C = 5

C = -5/1.5

C ≈ -3.33

The speed of the cyclist is approximately -3.33 km/h. However, since speed cannot be negative, this value is not valid.

Therefore, there is no valid solution to this problem.

Conclusion

Based on the given information, we cannot determine the speed of the pedestrian and the cyclist. The problem does not have a valid solution.
