Пошаговое объяснение:

Из одного поселка в другой вышел лыжник со скоростью 200 м/мин. Через несколько минут, вслед за ним вышел второй лыжник со скоростью 300 м/мин. Через сколько минут второй лыжник догонит первого, если расстояние между лыжниками 500 м ?

1) 300 - 200 = 100 (м/мин) - скорость сближения при движении в догонку

2) 500 : 100 = 5 (минут) - второй лыжник догонит первого

iramazurk: ))) Пожалуйста
