Problem Analysis

To solve this problem, we need to determine the speed at which Sasha was walking. We are given that Oleg walked at a speed of 48 meters per minute and that Sasha caught up with him after 4 minutes.

Solution

Let's assume that Sasha's speed is x meters per minute. Since Sasha caught up with Oleg after 4 minutes, we can set up the following equation:

Distance covered by Oleg = Distance covered by Sasha

Oleg's distance = Sasha's distance

Speed of Oleg * Time taken by Oleg = Speed of Sasha * Time taken by Sasha

48 * 4 = x * 4

Simplifying the equation:

192 = 4x

Dividing both sides by 4:

x = 48

Therefore, Sasha was walking at a speed of 48 meters per minute.

Conclusion

Sasha was walking at a speed of 48 meters per minute.
