Question

От пристани в противоположных направлениях одновременно вышли два катера.Скорость одного 18 км/ч, скорость другого 16 км/ч. На каком расстоянии друг от друга они будут находиться через 2 ч?

Answer 1

1) 18 + 16 =34(км/ч) скорость удаления
2) 34 х 2 =68(км)  расстояние через два часа
              Ответ: 68 км.

Answer 2

Problem Analysis

We have two boats that start from opposite ends of a dock and move towards each other. The speed of one boat is 18 km/h, and the speed of the other boat is 16 km/h. We need to find the distance between them after 2 hours.

Solution

To find the distance between the two boats after 2 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each boat after 2 hours and then find the total distance between them.

Boat 1: - Speed: 18 km/h - Time: 2 hours - Distance = 18 km/h × 2 hours = 36 km

Boat 2: - Speed: 16 km/h - Time: 2 hours - Distance = 16 km/h × 2 hours = 32 km

The total distance between the two boats after 2 hours is the sum of the distances traveled by each boat:

Total Distance = Distance of Boat 1 + Distance of Boat 2 = 36 km + 32 km = 68 km

Therefore, the two boats will be 68 km apart after 2 hours.

Answer

The two boats will be 68 km apart from each other after 2 hours.
