Problem Analysis:
The task involves dividing decimals and adding zeros to the dividend as needed. The goal is to determine how long it took the student to solve each division problem, given that they completed 6 division problems in 3 minutes.
#### Key Information:
1.
Total time spent: 3 minutes.
2.
Number of problems solved: 6.
3.
Task: Divide decimals, add zeros to the dividend as needed, and complete the division process.
#### Objective:
Calculate the time taken per problem.
---
Step-by-Step Solution:
1.
Convert total time to seconds:
- 1 minute = 60 seconds.
- Total time = 3 minutes = \( 3 \times 60 = 180 \) seconds.
2.
Determine time per problem:
- Total time for 6 problems = 180 seconds.
- Time per problem = \( \frac{\text{Total time}}{\text{Number of problems}} \).
- Time per problem = \( \frac{180}{6} = 30 \) seconds.
---
Explanation:
The student completed 6 division problems in 3 minutes (180 seconds). By dividing the total time by the number of problems, we find that each problem took an average of 30 seconds to solve.
---
Final Answer:
\[
\boxed{30}
\] seconds per problem.
