Answer 2

Problem Analysis

We are given that two boys, Aleksha and Borya, are running a race. Aleksha runs for 15 seconds and covers a distance of 75 meters. Borya overtakes Aleksha and runs an additional 30 meters. We need to find the speed at which each boy is running.

Solution

To find the speed at which each boy is running, we can use the formula:

Speed = Distance / Time

Let's calculate the speed for each boy.

1. Aleksha: - Distance covered by Aleksha = 75 meters - Time taken by Aleksha = 15 seconds - Speed of Aleksha = 75 meters / 15 seconds = 5 meters per second

2. Borya: - Distance covered by Borya = 75 meters + 30 meters (as he overtakes Aleksha) - Time taken by Borya = 15 seconds - Speed of Borya = (75 meters + 30 meters) / 15 seconds = 105 meters / 15 seconds = 7 meters per second

Therefore, Aleksha runs at a speed of 5 meters per second, while Borya runs at a speed of 7 meters per second.

I hope this helps! Let me know if you have any further questions.
