В ванне есть два крана. Через первый кран вода наливается в ванну, а через второй вытекает из ванны.
Если открыть оба крана, то полная ванна опорожнится за 30 минут. Сколько минут будет наполняться ванна, если будет открыт только первый кран, и известно, что через второй кран полная ванна опорожнится на 5 минут(-ы) быстрее, чем первый кран наполнит пустую ванну.
За сколько минут второй кран опорожнит полную ванну?

Первый кран наполнит пустую ванну за
минут.​
