Question

ДОМАШНЕЕ ЗАДАНИЕ 9 Реши задачу, 60 км/ч, THERE нси Из двух городов одновременно навстречу друг другу выехали два автомобиля. Скорость одного — 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:

1) 60 * 2 = 120 (км) - проехал 1 до встречи со 2

2) 70 * 2 = 140 (км) - проехал 2 до встречи с 1

3) 120 + 140 = 260 (км) - расстояние между городами

Ответ: 260 км

Answer 2

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

Let's assume that the distance between the two cities is D km.

Since the two cars are traveling towards each other, their combined speed is the sum of their individual speeds. Therefore, the combined speed of the two cars is 60 km/h + 70 km/h = 130 km/h.

We know that the time taken for the cars to meet is 2 hours.

Using the formula distance = speed × time, we can calculate the distance traveled by each car before they meet:

- Distance traveled by the first car = 60 km/h × 2 h = 120 km - Distance traveled by the second car = 70 km/h × 2 h = 140 km

Therefore, each car traveled 120 km and 140 km, respectively, 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 = 120 km + 140 km = 260 km

Answer

Therefore, each car traveled 120 km and 140 km, respectively, before they met. The distance between the two cities is 260 km.
