Question

Два пловца поплыли одновременно навстречу друг другу с разных концов бассейна длина которого 200 м.один плыл со скоростью28м мин,другой 22м мин.Через сколько минут они встретятся ?Какое расстояние проплывёт до встречи каждый из пловцов?

Answer 1

28+22=50 м/мин скорость сближения
200:50=4 мин
28*4=112 м проплывет первый пловец
22*4=88 м проплывёт второй пловец
Ответ: через 4 мин. они встретятся;
112 м первый пловец; 88 м второй пловец

Answer 2

Problem Analysis

We have two swimmers who start swimming towards each other from opposite ends of a 200-meter pool. One swimmer swims at a speed of 28 meters per minute, while the other swims at a speed of 22 meters per minute. We need to determine how long it will take for them to meet and the distance each swimmer will have covered until the meeting point.

Solution

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

Let's calculate the time it will take for the swimmers to meet:

Swimmer 1's speed = 28 meters per minute Swimmer 2's speed = 22 meters per minute Total distance = 200 meters

The time it will take for the swimmers to meet is equal to the total distance divided by the sum of their speeds:

time = total distance / (swimmer 1's speed + swimmer 2's speed)

Let's calculate the time:

time = 200 meters / (28 meters per minute + 22 meters per minute)

time = 200 meters / 50 meters per minute

time = 4 minutes

Therefore, it will take 4 minutes for the swimmers to meet.

Now, let's calculate the distance each swimmer will have covered until the meeting point:

Swimmer 1's speed = 28 meters per minute Swimmer 2's speed = 22 meters per minute Time = 4 minutes

The distance covered by each swimmer can be calculated using the formula: distance = speed * time.

Distance covered by swimmer 1 = 28 meters per minute * 4 minutes = 112 meters Distance covered by swimmer 2 = 22 meters per minute * 4 minutes = 88 meters

Therefore, swimmer 1 will cover 112 meters and swimmer 2 will cover 88 meters until they meet.

Answer

The swimmers will meet after 4 minutes. Swimmer 1 will cover a distance of 112 meters, and swimmer 2 will cover a distance of 88 meters until they meet.
