Question

Маша и Наташа вышли из школы одновременно и пошли в противоположных направлениях.Маша со скоростью 80 м. в минуту.а Наташа 70 м. в мин.На сколько метров удалились девочки одна от другой за 1 минуту.Какое расстояние между девочками будет через 5 мин.

Answer 1

1) 80+70=150 м/мин. - скорость удаления
2) 150*1=150м - расстояние между девочками через 1мин.
3) 150*5=750 м - будет расстояние между девочками через 5 мин.

Answer 2

Problem Analysis

We are given that Masha and Natasha left school at the same time and walked in opposite directions. Masha walks at a speed of 80 m/min, while Natasha walks at a speed of 70 m/min. We need to find the distance between the girls after 1 minute and after 5 minutes.

Distance after 1 minute

To find the distance between Masha and Natasha after 1 minute, we need to calculate the total distance covered by both girls in that time.

Masha's distance after 1 minute = 80 m/min * 1 min = 80 meters.

Natasha's distance after 1 minute = 70 m/min * 1 min = 70 meters.

Since they are walking in opposite directions, the total distance between them after 1 minute is the sum of their individual distances:

Total distance between Masha and Natasha after 1 minute = 80 meters + 70 meters = 150 meters.

Distance after 5 minutes

To find the distance between Masha and Natasha after 5 minutes, we can use the same approach as above.

Masha's distance after 5 minutes = 80 m/min * 5 min = 400 meters.

Natasha's distance after 5 minutes = 70 m/min * 5 min = 350 meters.

Again, since they are walking in opposite directions, the total distance between them after 5 minutes is the sum of their individual distances:

Total distance between Masha and Natasha after 5 minutes = 400 meters + 350 meters = 750 meters.

Therefore, the distance between Masha and Natasha will be 150 meters after 1 minute and 750 meters after 5 minutes.
