Maryna spent more time writing per problem at the unit rate of 25 min. 1 problem.
Based on the tables, Maryna spent more time writing per problem compared to Sonia. The unit rate for Maryna is 25 minutes per problem, while Sonia's unit rate is 20 minutes per problem.
To answer this question, we need to calculate the unit rate of each writer by dividing the minutes of writing by the number of problems.
For Sonia:
Unit rate = Minutes of Writing / Number of Problems
For the given data, we can calculate the unit rate for each row:
- For the first row, 120 minutes of writing / 6 problems = 20 minutes per problem.
- For the second row, 360 minutes of writing / 18 problems = 20 minutes per problem.
- For the third row, 500 minutes of writing / 25 problems = 20 minutes per problem.
- For the fourth row, 1,200 minutes of writing / 60 problems = 20 minutes per problem.
So, Sonia spent 20 minutes per problem consistently.
For Maryna:
Unit rate = Minutes of Writing / Number of Problems
- For the first row, 200 minutes of writing / 8 problems = 25 minutes per problem.
- For the second row, 375 minutes of writing / 15 problems = 25 minutes per problem.
- For the third row, 500 minutes of writing / 20 problems = 25 minutes per problem.
- For the fourth row, 1,250 minutes of writing / 50 problems = 25 minutes per problem.
So, Maryna also spent 25 minutes per problem consistently.
Therefore, both Sonia and Maryna spent the same amount of time writing per problem, at a unit rate of 25 minutes per problem.
