Question

Из двух городок расстояние между которыми 1200 км выехали одновременно навстречу друг другу два автомобиля и встретились через шесть часов. Первый автомобиль ехал со скоростью 98 километров в час. С какой скоростью ехал второй автомобиль? Плиз решение и пояснения! СРОЧНО!!! Даю 99 баллов!!!

Answer 1

1)98*6=588 км проехал первый
2)1200-588=612 км проехал второй
3)612:6=102 км/ч скорость второго авто

Answer 2

Problem Analysis

We are given that two cars start from two different towns and travel towards each other. The distance between the towns is 1200 km. The first car travels at a speed of 98 km/h. We need to find the speed of the second car.

Solution

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

We know that the time taken by both cars to meet is 6 hours.

The total distance traveled by the first car is the sum of the distances traveled by both cars. Since they are traveling towards each other, the sum of the distances is equal to the total distance between the towns, which is 1200 km.

Using the formula distance = speed × time, we can write the equation:

98 km/h × 6 hours + x km/h × 6 hours = 1200 km

Simplifying the equation, we get:

588 km + 6x km = 1200 km

Subtracting 588 km from both sides, we get:

6x km = 612 km

Dividing both sides by 6, we find:

x km/h = 102 km/h

Therefore, the second car was traveling at a speed of 102 km/h.

Answer

The second car was traveling at a speed of 102 km/h.

Explanation

The first car travels at a speed of 98 km/h, and the two cars meet after 6 hours. By using the formula distance = speed × time, we can set up an equation to find the speed of the second car. Solving the equation, we find that the second car was traveling at a speed of 102 km/h
