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
