Question

От двух пристаней одновременно отошли навстречу друг другу два теплохода. Один из них шел со скоростью 22 км/ч, другой 18 км/ч. Через 3 часа теплоходы встретились. Какое расстояние между пристанями.

Answer 1

22+18=40 км/ч скорость сближения
40*3=120 км между пристанями

Answer 2

1)22+18=40(км\ч)-скорость сближения
2)40х3=120

Answer 3

Problem Analysis

We have two ships that start from two different piers and move towards each other. The first ship has a speed of 22 km/h, while the second ship has a speed of 18 km/h. After 3 hours, the ships meet each other. We need to find the distance between the piers.

Solution

To find the distance between the piers, we can use the formula: distance = speed * time.

Let's calculate the distance traveled by each ship in 3 hours:

- The first ship traveled 22 km/h * 3 h = 66 km. - The second ship traveled 18 km/h * 3 h = 54 km.

Since the ships meet each other, the total distance between the piers is the sum of the distances traveled by each ship:

Total distance = 66 km + 54 km = 120 km.

Therefore, the distance between the piers is 120 km.

Answer

The distance between the piers is 120 km.
