Question

Два автомобиля выехали навстречу друг другу скорость первого была x- км/что. Скорость второго 64 км/что. Какое расстояние s было между ними пр-во начальник, если они встретились через 4 часа? Плиз,даю 10 баллов

Answer 1

Х×64=64х
64х×4=256×
64х×4=256
64х=256÷4
64х=64
х=64

Answer 2

1) 64*4=256(км) s второго
2)256*2=512(км) расстояние
ответ 512 км расстояни перваначально

Answer 3

Problem Analysis

Two cars are traveling towards each other. The speed of the first car is given as "x" km/h, and the speed of the second car is 64 km/h. We need to find the distance between them when they meet after 4 hours.

Solution

To find the distance between the two cars, we can use the formula: distance = speed * time.

Let's calculate the distance traveled by each car after 4 hours.

The first car travels at a speed of "x" km/h for 4 hours, so the distance traveled by the first car is 4x km.

The second car travels at a speed of 64 km/h for 4 hours, so the distance traveled by the second car is 64 * 4 = 256 km.

When the two cars meet, the sum of the distances traveled by both cars will be equal to the total distance between them.

Therefore, we can set up the equation: 4x + 256 = total distance.

To find the total distance, we need to solve this equation for "x".

Let's solve the equation:

4x + 256 = total distance

Subtract 256 from both sides:

4x = total distance - 256

Divide both sides by 4:

x = (total distance - 256) / 4

Now we have an equation to find the value of "x" in terms of the total distance.

Since we don't have the exact value of the total distance, we cannot calculate the exact value of "x" or the exact distance between the two cars. We can only express the distance in terms of the total distance.

Please provide the value of the total distance, and I can calculate the value of "x" and the distance between the two cars based on that.
