Question

Хочу проверить, правильно ли я решила задачу. Тюлень несколько раз нырял под лед за пищей. Первый раз он пробыл под водой 10 минут, второй раз 15, но ничего не нашел. Сколько минут пробыл тюлень под водой за этот день, если за остальные 20 минут он нашел еду и больше не нырял?

Answer 1

10 мин - пробыл под водой первый раз
15 мин - пробыл под водой второй раз
10 + 15 = 25 мин
Ответ: про водой в этот день он пробыл 25 минут

Answer 2

Problem Analysis

The problem states that a seal dived under the ice multiple times in search of food. The seal stayed underwater for 10 minutes on the first dive, 15 minutes on the second dive, and found food during the remaining 20 minutes, without diving again. We need to determine how many minutes the seal spent underwater in total on that day.

Solution

To find the total time the seal spent underwater, we need to add up the durations of all its dives. The seal spent 10 minutes on the first dive and 15 minutes on the second dive. Since it found food during the remaining 20 minutes and did not dive again, we can conclude that it did not spend any additional time underwater.

Therefore, the seal spent a total of 25 minutes underwater on that day.
