Пусть скорость второго пешехода равна Х км/час
Тогда скорость второго пешехода равна 2/3 Х км/час
Время движения 30 минут или 1/2 часа
Расстояние, которое за 30 минут второй пешеход = 2/3 Х * 1/2
Расстояние, которое первый пешеход = 1/2 Х
Вместе они км. Составим уравнение 1/2 Х + 2/3 Х * 1/2 = 5
1/2 Х + 2/6 Х = 5
Приводим к общему знаменателю
3Х+2Х=30
5Х=30
Х=6 км/час - это скорость второго пешехода. Скорость первого 2/3*6=4 км/час.
Первый за 30 минут (или 1/2 часа км, второй 6 * 1/2 = 3 км.
Вместе они км.
