Question

Из двух городов, расстояние между которыми 65 км, выехали одновременно в противоположных направлениях два автомобиля. Один из них шел со скоростью 80км/ч, а другой 120км/ч. На каком расстоянии друг от друга будут автомобили через три часа после выезда?

Answer 1

Сначала узнаем общую скорость автомобилей:
1) 120+80=200(км/ч)
Затем узнаем скорость умножаем на время, чтобы узнать расстояние:
2) 200×3=600(км)-расстояние
Ответ: 600 км будет между автомобилями через 3 часа.

Answer 2

(80*3)-(120*3)-65=55
Если не правильно простите.

Answer 3

Problem Analysis

We have two cars that start at the same time from two different cities, traveling in opposite directions. The first car is traveling at a speed of 80 km/h, and the second car is traveling at a speed of 120 km/h. We need to determine the distance between the two cars after three hours.

Solution

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

Let's assume that the distance traveled by the first car is D1 and the distance traveled by the second car is D2.

The formula to calculate distance is:

Distance = Speed × Time

For the first car: D1 = Speed1 × Time D1 = 80 km/h × 3 hours D1 = 240 km For the second car: D2 = Speed2 × Time D2 = 120 km/h × 3 hours D2 = 360 km Now, we need to find the total distance between the two cars. Since they are traveling in opposite directions, we can add the distances traveled by each car:

Total Distance = D1 + D2 Total Distance = 240 km + 360 km Total Distance = 600 km

Therefore, the two cars will be 600 km apart after three hours.

Answer

The two cars will be 600 km apart after three hours.
