Problem Analysis

We are given that Bulat and Sanzhar simultaneously left their homes and headed towards a stadium. The distance between their homes is 200 meters. Bulat lives farther and moves at a speed of 175 m/min, while Sanzhar walks at a speed of 75 m/min. We need to determine how long it will take for Bulat to catch up to Sanzhar.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between Bulat and Sanzhar is the difference between their individual speeds. In this case, the relative speed is 175 m/min - 75 m/min = 100 m/min.

Since Bulat is trying to catch up to Sanzhar, we can consider their motion as a race. The distance between them is 200 meters, and the relative speed is 100 m/min. To find the time it takes for Bulat to catch up to Sanzhar, we can use the formula:

Time = Distance / Relative Speed

Substituting the given values, we have:

Time = 200 meters / 100 m/min

Simplifying, we find:

Time = 2 minutes

Therefore, it will take Bulat 2 minutes to catch up to Sanzhar.

Answer

Bulat will catch up to Sanzhar in 2 minutes.
