Question

Два пловца спрыгнули прыгнули одновременно с лодки и поплыли по реке в противоположных направлениях: первый со скоростью 90 метров в минуту, а второй со скоростью 40 метров в минуту. Сколько метров проплывет второй пловец когда первый проплывёт 270 метров?ПОМОГИТЕ ПОЖАЛУЙСТО!!!!

Answer 1

Первый пловец проплывет 270 м за 270/90=3 минуты
Второй пловец за три минуты проплывет 40*3=120 метров

Answer 2

Problem Analysis

We have two swimmers who jump off a boat and start swimming in opposite directions. The first swimmer swims at a speed of 90 meters per minute, while the second swimmer swims at a speed of 40 meters per minute. We need to determine how many meters the second swimmer will have swum when the first swimmer has swum 270 meters.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between the two swimmers is the sum of their individual speeds. In this case, the relative speed is 90 + 40 = 130 meters per minute.

We can calculate the time it takes for the first swimmer to swim 270 meters by dividing the distance by the speed: 270 / 90 = 3 minutes.

Now, we can calculate the distance the second swimmer will have swum in 3 minutes at a speed of 130 meters per minute. We can use the formula distance = speed × time: distance = 40 × 3 = 120 meters.

Therefore, the second swimmer will have swum 120 meters when the first swimmer has swum 270 meters.

Answer

The second swimmer will have swum 120 meters when the first swimmer has swum 270 meters.

Explanation

When the first swimmer swims at a speed of 90 meters per minute and the second swimmer swims at a speed of 40 meters per minute, the second swimmer will have swum 120 meters when the first swimmer has swum 270 meters. This can be calculated using the concept of relative speed and the formula distance = speed × time. The relative speed between the two swimmers is 130 meters per minute (90 + 40), and the time it takes for the first swimmer to swim 270 meters is 3 minutes (270 / 90). Therefore, the second swimmer will have swum 120 meters (40 × 3) when the first swimmer has swum 270 meters.
