Answer 2

Problem Analysis

We are given that Petya is chasing Seryozha, who is walking at a speed of 100 m/min. The initial distance between them is 300 m, and Petya's speed is 160 m/min. We need to determine how many minutes it will take for Petya to catch up to Seryozha.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between Petya and Seryozha is the difference between their speeds. In this case, it is 160 m/min - 100 m/min = 60 m/min.

The time it takes for Petya to catch up to Seryozha can be calculated by dividing the initial distance between them by their relative speed. In this case, it is 300 m / 60 m/min = 5 minutes.

Therefore, it will take Petya 5 minutes to catch up to Seryozha.

Answer

Petya will catch up to Seryozha in 5 minutes.
