Question

Два лыжника начали двигаться одновременно от одного и того же флажка в противоположные стороны. один лыжник бежал со скоростью 4 м/с, а другой со скоростью 5 м/с. найди скорость удаления лыжников

Answer 1

Скорость удаления лыжников 4+5=9 м/c

Answer 2

Calculation of the Speed of Separation of Skiers

To find the speed of separation of the skiers, we need to calculate the relative velocity between them. The relative velocity is the difference between the velocities of the two skiers.

Given: - Skier 1's velocity = 4 m/s - Skier 2's velocity = 5 m/s

To find the speed of separation, we subtract the velocity of Skier 1 from the velocity of Skier 2:

Speed of separation = Skier 2's velocity - Skier 1's velocity

Substituting the given values:

Speed of separation = 5 m/s - 4 m/s = 1 m/s

Therefore, the speed of separation between the two skiers is 1 m/s.
