Переведем 1,2 м/с в м/ч.если в 1 часе 3600 секунд,то: 1,2*3600=4320 метров в час.за 3,8 часа он пройдёт 16416 метров. (3,8*4320) теперь сделаем тоже самое с 0,9 м/с 0,9*3600=3240 метров в час.за 2,2 часа он пройдёт 7128 метров. (2,2*3240) всего он прошёл 23544 метра (16416+7128) за 6 часов (3,8+2,2). его средняя скорость была: 23544/6=3924 метров в час.если переводить в м/с,то: 3924/3600=1,09 м/с ответ: 1,09 м/с p.s.вообще можно было решить быстрее: 3,8*1,2+2,2*0,9 / 6 = 1,09 (м/с) давно закончил школу и не уверен,что правильно будет перемножать "часы" и "секунды",хотя ответ получится одинаковым.
