Question

Решите задачу с вопросами Из двух посёлков, расстояние между которыми 58 км, вышли одновременно в противоположных направлениях два автомобиля. Один из них шёл со скоростью 85 км/ч, а другой-110км/ч. На каком расстоянии друг от друга будут автомобили через 3 часа после начала движения?

Answer 1

85+110=195км/ч скорость двух авто
195х3=585км проехали два авто за 3ч.
585+58=643 расстояние между двумя авто

Answer 2

Problem Analysis

We have two cars starting simultaneously from two villages that are 58 km apart. One car is traveling at a speed of 85 km/h, and the other car is traveling at a speed of 110 km/h. We need to find the distance between the two cars after 3 hours.

Solution

To find the distance between the two cars after 3 hours, we need to calculate the total distance traveled by each car.

The first car is traveling at a speed of 85 km/h. Therefore, in 3 hours, it will cover a distance of 85 km/h * 3 h = 255 km.

The second car is traveling at a speed of 110 km/h. Therefore, in 3 hours, it will cover a distance of 110 km/h * 3 h = 330 km.

Since the two cars are traveling in opposite directions, the distance between them after 3 hours will be the sum of the distances covered by each car. Therefore, the distance between the two cars after 3 hours will be 255 km + 330 km = 585 km.

Answer

After 3 hours, the two cars will be at a distance of 585 km from each other.
