Ответ:

10 км такое расстояние будет между ними через 2 часа

Пошаговое объяснение:

если 5 км/ч это 1/2 скорости велосипедиста,то тогда скорость велосипедиста :

5:1/2=5 * 2/1=10 км/ч -скорость велосипедиста

10*2=20 км проедет за 2 часа велосипедист

5*2=10 км пройдет пешеход за 2 часа

20-10=10 км- такое расстояние будет между ними через 2 часа
