Question

Два автомабиля елали с одинаковой скоростью Первый был в пути 8 часов,второй-3 часа.Первый проехал на 320 км больше,чем второй.Сколько километров проехал каждый автомобиль?

Answer 1

1)8-3=5
2)320:5=64
3)64*3=192
4)192+320=512

Answer 2

1)8-3=5(ч)-1 автомобиль был в пути бодьше.
2)320:5=64(км)- они проезжали за 1 час.
3)64*8=512(км)- проехал 1 автомобиль.
4)64*3=192(км)- проехал 2 автомобиль.

Answer 3

Problem Analysis

We are given two cars that traveled at the same speed. The first car took 8 hours to reach its destination, while the second car took 3 hours. The first car traveled 320 km more than the second car. We need to find out how many kilometers each car traveled.

Solution

Let's assume the distance traveled by the second car is x km. Since the first car traveled 320 km more than the second car, the distance traveled by the first car is x + 320 km.

We know that speed is equal to distance divided by time. Since both cars traveled at the same speed, we can set up the following equation:

Speed of the first car = Speed of the second car

Using the formula for speed, we have:

Distance of the first car / Time taken by the first car = Distance of the second car / Time taken by the second car

Substituting the values we have:

(x + 320) / 8 = x / 3

To solve this equation, we can cross-multiply:

3(x + 320) = 8x

Simplifying the equation:

3x + 960 = 8x

960 = 8x - 3x

960 = 5x

x = 960 / 5

x = 192

Therefore, the second car traveled 192 km, and the first car traveled 192 + 320 = 512 km.

Answer

The second car traveled 192 km, and the first car traveled 512 km.
