Question

Расстояние между лодкой и байдаркой 285м. Они одновременно поплыли в противоположных направлениях. Лодка плывёт со скоростью 57м\мин, а байдарка-со скоростью 76м\мин. На каком расстоянии друг от друга они окажутся через 12 минут?

Answer 1

1) 57 + 76 = 133 м/мин скорость удаления друг от друга
2) 133 * 12 = 1596 м проедут за 12 мин
3) 1596 + 285 = 1881 метров станет между ними

Problem Analysis

We are given that the distance between a boat and a kayak is 285 meters. They start moving in opposite directions simultaneously. The boat has a speed of 57 m/min, and the kayak has a speed of 76 m/min. We need to find the distance between them after 12 minutes.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's calculate the distance covered by the boat and the kayak after 12 minutes.

The boat's speed is 57 m/min, so in 12 minutes, it will cover a distance of 57 m/min × 12 min = 684 meters.

The kayak's speed is 76 m/min, so in 12 minutes, it will cover a distance of 76 m/min × 12 min = 912 meters.

Since they are moving in opposite directions, the total distance between them will be the sum of the distances covered by the boat and the kayak: 684 meters + 912 meters = 1596 meters.

Therefore, after 12 minutes, the boat and the kayak will be 1596 meters apart from each other.

Answer

After 12 minutes, the boat and the kayak will be 1596 meters apart from each other.
