Question

Два автомобиля выехали одновременно навстречу друг другу из двух пунктов,растояние между которыми 800км,и через 4 часа встретились.Один автомобиль ехал со сскоростью 110 км/ч. Определи скорость другого автомобиля.

Answer 1

1) 110 * 4 = 440 (км) проехал один из автомобилей до места встречи;
2) 800 - 440 = 360 ( км) проехал другой автомобиль до места встречи;
3) 360 : 4 = 90 (км/ч) скорость другого автомобиля.
Отвеь: 90 км/ч

Answer 2

Problem Analysis

We have two cars that start at the same time from two different points and meet after 4 hours. The distance between the two points is 800 km. One car is traveling at a speed of 110 km/h. We need to determine the speed of the other car.

Solution

Let's assume the speed of the second car is x km/h.

We know that the distance traveled by both cars is the same, as they meet each other. Therefore, we can set up the following equation:

Distance traveled by the first car = Distance traveled by the second car

Speed of the first car * Time taken by the first car = Speed of the second car * Time taken by the second car

110 km/h * 4 hours = x km/h * 4 hours

Simplifying the equation:

440 km = 4x

Dividing both sides by 4:

x = 110 km/h

Therefore, the speed of the second car is 110 km/h.
