Answer 1

To determine who spent more time writing per problem, we need to calculate the unit rate (minutes spent per problem) for both Sonia and Maryna.

For Sonia:

1. 6 problems = 120 minutes → 120 minutes / 6 problems = 20 minutes/problem
2. 18 problems = 360 minutes → 360 minutes / 18 problems = 20 minutes/problem
3. 25 problems = 500 minutes → 500 minutes / 25 problems = 20 minutes/problem
4. 60 problems = 1,200 minutes → 1,200 minutes / 60 problems = 20 minutes/problem

Unit rate for Sonia: 20 minutes/problem

For Maryna:

1. 8 problems = 200 minutes → 200 minutes / 8 problems = 25 minutes/problem
2. 15 problems = 375 minutes → 375 minutes / 15 problems = 25 minutes/problem
3. 20 problems = 500 minutes → 500 minutes / 20 problems = 25 minutes/problem
4. 50 problems = 1,250 minutes → 1,250 minutes / 50 problems = 25 minutes/problem

Unit rate for Maryna: 25 minutes/problem

Conclusion:

Sonia spent 20 minutes per problem, while Maryna spent 25 minutes per problem. Thus, Maryna spent more time writing per problem.

The correct response is: Maryna spent more time writing per problem at the unit rate of 25 min. 1 problem.
