Question

На подготовку уроков девочка затратила 2 часа. 40% ушло на решение задач, 35% на выполнение упражнений по русскому, а остальное время было посвящено географии. Сколько минут затрачено на каждый предмет?

Answer 1

1ч = 60 мин
2ч = 120 мин
120*40:100= 48 мин на задачи
120*35:100=42 мин на русский
120-(48+42)= 120-90= 30 мин на географию

Answer 2

Calculating Time Spent on Each Subject

To calculate the time spent on each subject, we can use the following steps:

1. Calculate the Total Time Spent on Lesson Preparation: - The girl spent 2 hours on lesson preparation.

2. Calculate Time Spent on Solving Problems: - 40% of 2 hours is spent on solving problems. - 40% of 120 minutes (2 hours) = 48 minutes.

3. Calculate Time Spent on Russian Exercises: - 35% of 2 hours is spent on Russian exercises. - 35% of 120 minutes (2 hours) = 42 minutes.

4. Calculate Time Spent on Geography: - The remaining time is spent on geography. - Total time - (time spent on solving problems + time spent on Russian exercises) = Time spent on geography - 120 minutes - (48 minutes + 42 minutes) = 30 minutes.

Conclusion

The time spent on each subject is as follows: - Solving Problems: 48 minutes - Russian Exercises: 42 minutes - Geography: 30 minutes
