Если пешеходы выходят одновременно и встреча происходит на середине пути, то пешеходы движутся с одинаковой скоростью.
9+4=13(км до встречи І пешеход
28-13-15(км до встречи ІІ пешеход
t=S:V
х км/ч - начальная скорость обоих пешеходов
15/х (час) - время в пути ІІ пешехода
9/х+4/(х+1) +1 (час) - время в пути І пешехода
Время в пути до встречи одинаковое.
15/х=9/х+4/(х+1) + 1, общий знаменатель х(х+1)
15х+15-9х-9-4х-х²-х=0
х²-х-6=0
D=b²-4ac
D=1+24=25
х=(1+5):2=3(км/ч) - скорость ІІ пешехода
