Question

Из одного почтового отделения одновременно в противоположных направлениях вышли два почтальона.Скорость одного из них 60 м/мин,другого- 70м/мин.На каком расстоянии друк от друга будут почтальоны через 10 мин. 1 способ1)2)3) 2 способ1)2)3)

Answer 1

1)60+70=130

130*10=1300

 

 

2)60*10=600

70*10=700

700+600=1300 

Answer 2

1 способ

1)60*10=600

2)70*10=700

3)700+600=1300м

2 способ

х=60*10+70*10

х=1300м

Answer 3

Problem Statement

Два почтальона одновременно вышли из одного почтового отделения в противоположных направлениях. Скорость одного из них составляет 60 м/мин, а другого – 70 м/мин. На каком расстоянии друг от друга будут почтальоны через 10 минут?

Solution 1: Using Relative Speed

To find the distance between the two postmen after 10 minutes, we can use the concept of relative speed.

Step 1: Calculate the relative speed of the two postmen. - The relative speed of the two postmen is the sum of their individual speeds, as they are moving in opposite directions. - Relative speed = Speed of postman 1 + Speed of postman 2 - Relative speed = 60 m/min + 70 m/min

Step 2: Use the formula Distance = Speed × Time to find the distance covered by the postmen in 10 minutes. - Distance = Relative speed × Time - Distance = (60 m/min + 70 m/min) × 10 min

Solution 2: Using Individual Distances

Alternatively, we can calculate the distances covered by each postman individually and then find the total distance between them.

Step 1: Calculate the distance covered by each postman in 10 minutes. - Distance covered by postman 1 = Speed of postman 1 × Time - Distance covered by postman 2 = Speed of postman 2 × Time

Step 2: Find the total distance between the two postmen by adding their individual distances.

Conclusion

You can use either of the two methods to find the distance between the two postmen after 10 minutes. Both methods will give you the same result.

Let's calculate the distance using the first method:

Using Relative Speed: - Relative speed = 60 m/min + 70 m/min = 130 m/min - Distance = Relative speed × Time = 130 m/min × 10 min = 1300 meters

So, the two postmen will be 1300 meters apart after 10 minutes.
