Question

Два мальчика одновременно побежали навстречу друг другу по спортивной дорожке, длина которой 100 м. Они встретились через 10 сек, первый бежал со скоростью 4 м/сек с какой скоростью бежал второй мальчик? Если можете запишите в таблицу V T S

Answer 1

1) 10*4=40(м)-пробежал первый мальчик         2)100-40=60(м)-пробежал второй мальчик      3)60:10=6(м/сек)-скорость второго мальчика.

Answer 2

Problem Analysis

We are given that two boys are running towards each other on a sports track with a length of 100 meters. They meet after 10 seconds. We need to determine the speed at which the second boy is running.

Solution

Let's denote the speed of the first boy as V1 and the speed of the second boy as V2. We know that the total distance covered by both boys is 100 meters, and they meet after 10 seconds.

We can use the formula distance = speed × time to calculate the distance covered by each boy.

For the first boy: V1 × 10 = 100

Simplifying the equation, we find: V1 = 100 / 10 = 10 m/s

Since the boys are running towards each other, the distance covered by the second boy is also 100 meters.

For the second boy: V2 × 10 = 100

Simplifying the equation, we find: V2 = 100 / 10 = 10 m/s

Therefore, the second boy is also running at a speed of 10 m/s.

Table

Here is the information presented in a table format:

| Boy | Speed (m/s) | Time (s) | Distance (m) | |-----|-------------|----------|--------------| | 1 | 10 | 10 | 100 | | 2 | 10 | 10 | 100 |

Conclusion

The second boy is running at a speed of 10 m/s.
