Ответ:

Изначально требуется определить, какое количество воды выкачал каждый из насосов за указанное время.

Чтобы это сделать, нужно время работы насосов умножить на их производительность.

Будет:

4 * 158 = 632 ведра (выкачал 1 насос).

3 * 169 = 507 ведер (выкачал 2 насос).

Находим разницу количества выкачанных ведер.

Отнимаем от 632 ведер 507.

Получим:

632 - 507 = 125 ведер.

Ответ:

Первый насос выкачал на 125 ведер воды больше, чем второй.

Ответ:

1 выкачал больше,на 125 ведер

Пошаговое объяснение:

1)R(работа) t(Время) v(Скорость)

$I$ ? в 4ч 158в/ч

$II$ ? в 3ч 169в/ч

2)1)4 * 158 = 632(в)R1

2)2)3 * 169 =507(в)R2

2)3)632 - 507 = на 125(в) 1 насос выкачал больше 2-ого

Ответ:

1 выкачал больше,на 125 ведер
