Question

два туриста вышли с базы в противоположных направлениях. один пошел в лес за грибами со скоростью 6 км/ч,а другой пошел к озеру на рыбалку со скоростью4 км/ч.на какое расстояние друг от друга они удалились через 30 минут?

Answer 1

1тур ,скорость=6км/ч
2тур, скорость =4км/ч
Идут в разные стороны;
Расстояние через 30мин=?

1час=60мин; 60:2=30мин=1/2часа
Делим на 2 скорость

1)) 6:2=3км за полчаса пройдёт 1 тур
2)) 4:2=2км за полчаса пройдёт 2 тур
3)) 3+2=5 км будет между ними

Ответ: за 30 минут туристы удалятся на 5км друг от друга


Второе решение
1)) 6+4=10км в час скорость удаления
2)) 10:2= 5км будет через полчаса

Ответ: за полчаса туристы удалятся на 5 км друг от друга

Answer 2

Problem Analysis

Two tourists started walking in opposite directions from a base. One went into the forest to pick mushrooms at a speed of 6 km/h, while the other went to the lake for fishing at a speed of 4 km/h. We need to calculate the distance between them after 30 minutes.

Solution

To find the distance between the two tourists after 30 minutes, we need to calculate the total distance covered by each tourist in that time.

Let's start by calculating the distance covered by the first tourist who went into the forest. We know that the speed of the first tourist is 6 km/h, and they walked for 30 minutes. To find the distance, we can use the formula:

Distance = Speed × Time

Converting the time from minutes to hours (30 minutes = 0.5 hours), we can calculate the distance covered by the first tourist:

Distance1 = 6 km/h × 0.5 h

Next, let's calculate the distance covered by the second tourist who went to the lake. We know that the speed of the second tourist is 4 km/h, and they also walked for 30 minutes. Using the same formula as before, we can calculate the distance covered by the second tourist:

Distance2 = 4 km/h × 0.5 h

Finally, to find the distance between the two tourists, we need to subtract the distance covered by one tourist from the distance covered by the other:

Distance between the tourists = |Distance1 - Distance2|

Let's calculate the distances:

Distance1 = 6 km/h × 0.5 h = 3 km

Distance2 = 4 km/h × 0.5 h = 2 km

Distance between the tourists = |3 km - 2 km| = 1 km

Therefore, the two tourists have moved 1 kilometer away from each other after 30 minutes.

Answer

The two tourists have moved 1 kilometer away from each other after 30 minutes.
