ДОМАШНЕЕ ЗАДАНИЕ 9 Реши задачу. Из двух городов одновременно навстречу друг другу выехали два автомобиля. Скорость одного - 60 км/ч, скорость другого - 70 км/ч. Какое расстояние прое- хал каждый из них до встречи, если встреча произо- шла через 2 ч? Какое расстояние между городами? с чертежам и на тетради чтобы я могла списать пж даю 30балов ​

Answer 1

Пошаговое объяснение:

70*2=140 (км) проехал первый.

60*2=120 (км) проехал второй .

120+140= 260(км) расстояние между городами.

Ответ: 260 (км) расстояние между городами.

Answer 2

Problem Analysis

We have two cars traveling towards each other from two different cities. The speed of one car is 60 km/h, and the speed of the other car is 70 km/h. We need to find the distance each car traveled before they met, as well as the distance between the two cities.

Solution

To find the distance each car traveled before they met, we can use the formula:

Distance = Speed × Time

Since both cars traveled for 2 hours before they met, we can calculate the distance each car traveled as follows:

Car 1: - Speed: 60 km/h - Time: 2 hours - Distance = 60 km/h × 2 hours = 120 km

Car 2: - Speed: 70 km/h - Time: 2 hours - Distance = 70 km/h × 2 hours = 140 km

Therefore, Car 1 traveled 120 km, and Car 2 traveled 140 km before they met.

To find the distance between the two cities, we can add the distances traveled by both cars:

Distance between the two cities = Distance traveled by Car 1 + Distance traveled by Car 2 = 120 km + 140 km = 260 km

Therefore, the distance between the two cities is 260 km.

Conclusion

- Car 1 traveled 120 km before the meeting point. - Car 2 traveled 140 km before the meeting point. - The distance between the two cities is 260 km.
