Question

Автобус и автомобиль выехали одновременно из 2 городов навстречу друг другу скорость автомобиля 70 километров в час а автобуса 60 километров в час через сколько часов они встретятся если расстояние между городами 260 километров

Answer 1

1)60+70=130 общая скорость
2)260:130=2- через сколько он встретяться
Ответ 2 часа

Answer 2

Ответ:

Пошаговое объяснение:

Автомобиль-70км/ч

Автобус-60км/ч

Через сколько часов они встретятся,если расстояние между городами 260км?

70+60=130(км/ч)-скорость сближения

260:130=2(ч)-время в пути до встречи

Ответ:они встретятся через 2 часа

Answer 3

Problem Analysis

We are given that a bus and a car start from two different cities and travel towards each other. The car has a speed of 70 kilometers per hour, while the bus has a speed of 60 kilometers per hour. We need to determine how many hours it will take for them to meet if the distance between the cities is 260 kilometers.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it will take for the car and the bus to meet.

The car's speed is 70 kilometers per hour, and the distance between the cities is 260 kilometers. Therefore, the time it will take for the car to travel the distance is:

car_time = distance / car_speed = 260 / 70 = 3.714 hours

Similarly, the bus's speed is 60 kilometers per hour, and the distance between the cities is 260 kilometers. Therefore, the time it will take for the bus to travel the distance is:

bus_time = distance / bus_speed = 260 / 60 = 4.333 hours

Since both the car and the bus started at the same time, the time it will take for them to meet is the maximum of the two times:

meeting_time = max(car_time, bus_time) = max(3.714, 4.333) = 4.333 hours

Therefore, it will take approximately 4.333 hours for the car and the bus to meet.

Answer

It will take approximately 4.333 hours for the car and the bus to meet if they start from two different cities and travel towards each other at speeds of 70 kilometers per hour and 60 kilometers per hour, respectively, with a distance of 260 kilometers between the cities.
