Based on the data provided, here’s a breakdown of the statements regarding Maryna and Sonia's time spent writing per problem:
-
Maryna spent more time writing per problem at the unit rate of 25 min/problem.
- This would indicate that Maryna takes longer than 25 minutes per problem.
-
Sonia spent the same amount of time as Maryna at the unit rate of 25 min/problem.
- If true, this implies that both Sonia and Maryna take exactly 25 minutes per problem.
-
Sonia spent more time writing per problem at the unit rate of 20 min/problem.
- This suggests that Sonia takes longer than 20 minutes per problem.
-
Maryna spent less time writing per problem at the unit rate of 1 problem/25 min.
- This would mean Maryna takes less than 25 minutes per problem.
Based on this information, we can conclude the following:
- If Maryna is spending more time than Sonia based on the first statement, then Sonia's time must also be greater than 25 min/problem. This creates a contradiction.
- If you take the second statement to be true, then both would be equal to 25 mins. This indicates neither is spending more than 25 min/problem.
- The third and fourth statements can’t both be true if we are comparing the same metric.
Ultimately, without seeing exact times spent by Maryna and Sonia, we can analyze the statements but may not firmly conclude any single truth from them. We need specific data from the tables in question to confirm any of these statements accurately.
If more context or data is available, please provide the numerical values or specific details regarding the times each person spent, and I can assist further with the analysis.
