Question

Пункта А одновременно в противоположных направлениях выехали два автомобиля Через 3 часа расстояние между ними было равно 330 километров с какой скоростью двигался первый автомобиль если известно что скорость второго 75 километров в час

Answer 1

Надо узнать сколько проехал  второй автомобиль  3 х75=225 км                    330-225=105 км проехал первый автомобиль узнаем скорость 105:3=35 км вчас

Answer 2

Problem Analysis

We have two cars that started simultaneously in opposite directions. After 3 hours, the distance between them was 330 kilometers. We need to find the speed of the first car, given that the speed of the second car is 75 kilometers per hour.

Solution

Let's assume the speed of the first car is x kilometers per hour.

The distance covered by the first car in 3 hours is 3x kilometers.

The distance covered by the second car in 3 hours is 3 * 75 kilometers.

Since the cars are moving in opposite directions, the total distance covered by both cars is equal to the sum of their individual distances.

So, we can set up the equation:

3x + 3 * 75 = 330

Simplifying the equation:

3x + 225 = 330

Subtracting 225 from both sides:

3x = 330 - 225

3x = 105

Dividing both sides by 3:

x = 105 / 3

x = 35

Therefore, the speed of the first car is 35 kilometers per hour.

Answer

The first car was moving at a speed of 35 kilometers per hour.
