Two boys simultaneously ran towards each other along the sports track, the length of which is 300m

Two boys simultaneously ran towards each other along the sports track, the length of which is 300m. They met in 2 minutes. The first boy ran at a speed of 70 m / min. How fast was the second boy running?

We will solve this task in steps and explain each of them in detail.
1) 2 * 70 = 140 meters – the distance that the first boy ran at a speed of 70 meters per minute in 2 minutes of his movement;
2) 300 – 140 = 160 meters – the distance that the second boy ran in 2 minutes of his movement, since the boys ran towards each other, and the distance was 300 meters, and the first boy ran 140 meters;
3) 160: 2 = 80 meters per minute – the speed of the second boy, as he ran 160 meters in 2 minutes.
Answer: 80 meters per minute.
