Question

два туриста одновременно вышли из лагеря.первый шел на север со скоростью 6км /ч второй шёл на запад со скоростью 8 км/ч. каким будет расстояние между ними через 2 часа? помогите дам 20 баллов!!

Answer 1

Ответ:

Пошаговое объяснение:

v = корень( v1^2 + v2^2)

S = v*t =  корень( v1^2 + v2^2) *t =корень( 6^2 + 4^2) *3 ~ 21,63... км

Problem Analysis

Two tourists simultaneously leave a camp. The first tourist walks north at a speed of 6 km/h, while the second tourist walks west at a speed of 8 km/h. We need to determine the distance between them after 2 hours.

Solution

To find the distance between the two tourists after 2 hours, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the distance traveled by the first tourist after 2 hours is 6 km/h * 2 h = 12 km to the north, and the distance traveled by the second tourist after 2 hours is 8 km/h * 2 h = 16 km to the west. Therefore, we have a right triangle with sides of 12 km and 16 km.

Using the Pythagorean theorem, we can calculate the distance between the two tourists as follows:

Distance = √(12^2 + 16^2)

Let's calculate the distance using this formula:

Distance = √(144 + 256) = √400 = 20 km

Therefore, the distance between the two tourists after 2 hours will be 20 km.

Answer

The distance between the two tourists after 2 hours will be 20 km.
