Question

два всадника отправились из одного пункта одновременно в одном направлении. Скорость одного всадника 210 м/минуту а другого 180 м/минуту.Через сколько минут расстояние между всадниками станет равным 1500 м?​

Answer 1

А ----------------------------------- 1500 м ----------------------------- В

180 м/мин ----->

210 м/мин ------------>

1) 210 - 180 = 30 м/мин - скорость опережения одного всадника (или скорость отставания другого всадника;

2) 1500 : 30 = 150 : 3 = 50 мин - время движения.

Ответ: через 50 минут.

Answer 2

Ответ:

через 50 минут

Пошаговое объяснение:

Относительно медленного всадника, быстрый всадник удаляется от него на $210-180=30$ м/минуту. Соответственно, расстояние станет равным 1500 м через $1500:30=50$ минут

Answer 3

Problem Analysis

We have two riders who start from the same point simultaneously and travel in the same direction. The speed of one rider is 210 m/minute, and the speed of the other rider is 180 m/minute. We need to find out how many minutes it will take for the distance between the riders to become 1500 meters.

Solution

To solve this problem, we can set up an equation based on the relative speed of the two riders. The relative speed is the difference between their speeds.

Let's assume that it takes t minutes for the distance between the riders to become 1500 meters. During this time, the faster rider will cover a distance of 210t meters, and the slower rider will cover a distance of 180t meters.

According to the problem, the distance between the riders will be 1500 meters. So, we can set up the equation:

210t - 180t = 1500

Simplifying the equation:

30t = 1500

Dividing both sides of the equation by 30:

t = 50

Therefore, it will take 50 minutes for the distance between the riders to become 1500 meters.

Answer

It will take 50 minutes for the distance between the two riders to become 1500 meters.
