Question

Артём вышел из школы и направился к дому со скоростью 100 м/мин. Через 7 минут вышел Рубен и пошёл в противоположном направлении со скоростью 90 м/мин. Какое расстояние будет между мальчиками через 10 минут после выхода Артёма? Через 10 минут после выхода Рубена?

Answer 1

1) 10•100=1000м(Артем), 10-7=3мин. шел Рубен и прошел 3•90=270м, 1000+270=1270 расстояние между ними 2) 10•90=900м прошел Рубен, 10+7=17 время Артема, за которое он прошел 17•100=1700м, 900+1700=2600м расстояние между ними.

Answer 2

Calculation of Distance Between Artem and Ruben

To calculate the distance between Artem and Ruben after 10 minutes, we need to consider their speeds and the time elapsed.

Artem's speed is 100 m/min, and Ruben's speed is 90 m/min. After 7 minutes, Ruben starts walking in the opposite direction to Artem.

Let's break down the timeline:

1. Artem walks for 10 minutes at a speed of 100 m/min. 2. Ruben walks for 3 minutes (10 minutes - 7 minutes) at a speed of 90 m/min.

To calculate the distance between them, we can use the formula:

Distance = Speed x Time

For Artem: - Speed: 100 m/min - Time: 10 minutes

Distance traveled by Artem = 100 m/min x 10 min = 1000 meters.

For Ruben: - Speed: 90 m/min - Time: 3 minutes

Distance traveled by Ruben = 90 m/min x 3 min = 270 meters.

Since Ruben is walking in the opposite direction, we need to subtract his distance from Artem's distance to find the total distance between them:

Total distance between Artem and Ruben = Distance traveled by Artem - Distance traveled by Ruben = 1000 meters - 270 meters = 730 meters.

Therefore, the distance between Artem and Ruben after 10 minutes will be 730 meters.
