1) 4*2=8 (км) — прошёл пешеход за первые два часа.
2) 24-8=16 (км) — расстояние между пешеходом и велосипедистом.
3) 4+12=16 (км/ч) — общая скорость
4) 16:16=1 (ч) — через столько они встретятся.
5) не забываем, что пешеход два часа до этого прошёл 8 км.
2+1=3 (ч) — столько часов пешеход потратил на путь до велосипедиста.
