Question

Как решить задачу орёл и сокол полетели из одной точки в противоположных направлениях через какое время расстояние между ними станет равным километру если скорость орла 30м/с а скорость сокола 20м/с

Answer 1

1 км= 1000м
1000:(20+30)=20(сек)

Answer 2

Problem Analysis

We are given that an eagle and a falcon start flying from the same point in opposite directions. The eagle has a speed of 30 m/s, and the falcon has a speed of 20 m/s. We need to determine how much time it will take for the distance between them to become 1 kilometer.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume that the time it takes for the distance between the eagle and the falcon to become 1 kilometer is t seconds.

The distance traveled by the eagle in time t is given by: distance_eagle = speed_eagle × t.

The distance traveled by the falcon in time t is given by: distance_falcon = speed_falcon × t.

Since they are flying in opposite directions, the total distance between them is the sum of the distances traveled by the eagle and the falcon: distance_eagle + distance_falcon = 1 kilometer.

Substituting the values, we have: 30t + 20t = 1000 meters.

Simplifying the equation, we get: 50t = 1000.

Solving for t, we find: t = 1000 / 50 = 20 seconds.

Therefore, it will take 20 seconds for the distance between the eagle and the falcon to become 1 kilometer.

Answer

It will take 20 seconds for the distance between the eagle and the falcon to become 1 kilometer.
