Question

ПОЖАЛУЙСТА СРОЧНО 2. Два туриста одновременно вышли из лагеря. Первый шел на север со скоростью 5 км/ч, второй пел на запад со скоростью 4 км/ч. Каким будет расстояние между ними через 3 часа. (36)​

Answer 1

Ответ:

Объяснение:

5*3=15 км прошел турист на север;

4*3=12 км прошел турист на запад;

пути на север и запад - катеты прямоугольного треугольника, расстояние между концами пути - гипотенуза. По т. Пифагора -

√(15²+12²)=√396=3√41 км.

Answer 2

Distance between Two Tourists

To find the distance between the two tourists after 3 hours, we need to calculate the distance each tourist has traveled in that time.

The first tourist is walking north at a speed of 5 km/h. After 3 hours, they would have traveled a distance of 5 km/h * 3 hours = 15 km to the north.

The second tourist is walking west at a speed of 4 km/h. After 3 hours, they would have traveled a distance of 4 km/h * 3 hours = 12 km to the west.

To find the distance between them, we can use the Pythagorean theorem, which states that in a right-angled 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 between the two tourists is the hypotenuse of a right-angled triangle, with the northward distance as one side and the westward distance as the other side.

Using the Pythagorean theorem, we can calculate the distance between them:

Distance = sqrt((15 km)^2 + (12 km)^2)

Calculating this, we get:

Distance = sqrt(225 km^2 + 144 km^2) = sqrt(369 km^2) = 19.21 km

Therefore, the distance between the two tourists after 3 hours will be approximately 19.21 km.
