Question

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? ​

Answer 1

Ответ:

Пошаговое объяснение:

60×2=120км проехал 1 автомобиль за 2часа

70×2=140км проехал 2 автомобиль за 2часа

120+140=260км расстояние между городами

Answer 2

1) 60+70=130(км/ч)- общая скорость
2) 130•2=260(км)
Ответ: каждый из автомобилей проехал 260 км.

Answer 3

Problem Analysis

We are given that two cars start from two different cities and travel towards each other. 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 traveled by each car before they meet, as well as the distance between the two cities.

Solution

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

Distance = Speed × Time

Since the cars are traveling towards each other, their combined speed is the sum of their individual speeds. Let's calculate the distance traveled by each car:

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 each car:

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.

Answer

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