168 Таня и её подруга должны надписать 450 конвертов. Таня надписывает 46 конвертов в час, а её подруга — 42 конверта. Сколько конвертов останется им надписать через 2 ч совместной работы?

Решение 2. №168 (с. 55)

Для решения задачи необходимо выполнить три действия: найти общую скорость работы, вычислить количество сделанной работы за указанное время и, наконец, определить остаток.

1. Найдем, сколько конвертов Таня и её подруга надписывают вместе за один час (совместная производительность).

Для этого сложим их индивидуальные скорости:

$46 + 42 = 88$ (конвертов в час)

Вместе они надписывают 88 конвертов за час.

2. Теперь узнаем, сколько конвертов они надпишут за 2 часа совместной работы.

Для этого умножим их совместную производительность на время работы:

$88 * 2 = 176$ (конвертов)

За 2 часа они надпишут 176 конвертов.

3. Наконец, определим, сколько конвертов останется надписать.

Вычтем из общего количества конвертов то количество, которое они уже надписали:

$450 - 176 = 274$ (конверта)

Ответ: 274 конверта.
