Calculating the Duration of Independent Work

To calculate the duration of the independent work, we can use the information provided in the question. The lesson lasted 40 minutes, and during 5/8 of the lesson, the students were solving problems. This means the remaining time was dedicated to independent work.

Step 1: Calculate the time spent on problem-solving: - 5/8 * 40 minutes = 25 minutes

Step 2: Calculate the time spent on independent work: - Total lesson time - time spent on problem-solving - 40 minutes - 25 minutes = 15 minutes

Therefore, the independent work lasted 15 minutes.
