На момент выезда велосипедиста пешеход уже

5 км/ч * 1 час = 5 км

До встречи с велосипедистом на момент выезда осталось:

45 - 5 = 40 км

Скорость сближения:

5 + 15 = 20 км/час

Встретятся через:

40 км : 20 км/ч = 2 часа

Найдем, сколько пешеход до встречи от села:

1 + 2 = 3 часа

5 км/ч *3 = 15 км

Найдем, сколько проехал велосипедист от города до встречи с пешеходом:

15 км/ч * 2 = 30 км - от города

Найдем, какое расстояние до села осталось проехать велосипедисту на момент встречи с пешеходом:

45 км - 30 км = 15 км

До села на момент встречи осталось 15 км

А вопрос с подковыркой. Где бы пешеход с велосипедистом не встретились, расстояние до села будет у них одинаковое
