Question

Из двух городов расстояние между которыми 726 км, одновременно на встречу друг другу выехали два автомобиля. Один двигался со скоростью 67 километров в час. Найди скорость другого автомобиля если они встретились через 6 часов

Answer 1

726÷6=121(км/ч) скорость сближения
121-67=54(км/ч) скорость 2 автомобиля

Answer 2

Problem Analysis

We are given that two cars start simultaneously from two cities that are 726 km apart. One car is traveling at a speed of 67 km/h. We need to find the speed of the other car if they meet after 6 hours.

Solution

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

We can use the formula: distance = speed × time.

For the first car, the distance traveled is 67 km/h × 6 h = 402 km.

For the second car, the distance traveled is x km/h × 6 h = 6x km.

Since the total distance between the two cities is 726 km, we can write the equation: 402 km + 6x km = 726 km.

Simplifying the equation, we have: 6x km = 726 km - 402 km.

Solving for x, we get: 6x km = 324 km.

Dividing both sides of the equation by 6, we find: x km = 54 km/h.

Therefore, the speed of the second car is 54 km/h.

Answer

The speed of the second car is 54 km/h.
