Аня и Оля вышли одновременно из своих домов и пошли в школу. Через 15 минут Аня догнала Олю. Какое расстояние между домами девочек, если Аня шла со скоростью 80 м/мин, а Оля—со скоростью 65 м/мин?

Ответы

Автор ответа: markat

80-65=15 м/мин скорость сближения
15*15=225 м расстояние между домами

ИЛИ:

80*15=1200 м пройдет Аня
65*15=975 м пройдет Оля
1200-975=225 м расстояние между домами
