Question

Реши задачу вычисли и запиши ответ . Из одного и того же пункта одновременно в противоположных направлениях выехали два автомобиля . на каком расстоянии они окажутся через 3часа друг от друга , если скорость одного автомобиля 50км /ч скопость второго автомобиля 70км /ч

Answer 1

1 автомобиль - 50 км/ч
2-автомобиль - 70 км/ч
t (время)- 3 часа

1) 50•3=150 (км)- проехал первый автомобиль
2) 70•3=210 (км) - проехал второй автомобиль
3)150+210=360(км)
Ответ : 360 км расстояние первого автомобиля от второго

Answer 2

Problem Analysis

We have two cars that start from the same point and travel in opposite directions. We need to find the distance between them after 3 hours. The first car has a speed of 50 km/h, and the second car has a speed of 70 km/h.

Solution

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

The distance traveled by the first car can be calculated using the formula: distance = speed * time. Substituting the values, we get: distance1 = 50 km/h * 3 h.

Similarly, the distance traveled by the second car can be calculated using the same formula: distance2 = 70 km/h * 3 h.

To find the total distance between the two cars, we need to add the distances traveled by each car: total distance = distance1 + distance2.

Let's calculate the distances and find the total distance.

Calculation

- Distance traveled by the first car: distance1 = 50 km/h * 3 h = 150 km- Distance traveled by the second car: distance2 = 70 km/h * 3 h = 210 km- Total distance between the two cars: total distance = distance1 + distance2 = 150 km + 210 km = 360 km

Answer

The two cars will be 360 km apart after 3 hours.
