Answer 1

To determine who spent more time writing per problem and express it in unit rate form, we can interpret the provided responses:

1. Sonia spent the same time as Maryna per problem at the unit rate of 25 min. 1 problem.
2. Sonia spent more time writing per problem at the unit rate of 20 min. 1 problem.
3. Maryna spent less time writing per problem at the unit rate of 1 min. 25 problems, which translates to 0.04 min. 1 problem (or 4 seconds per problem).
4. Maryna spent more time writing per problem at the unit rate of 25 min. 1 problem.

From the details, we can assess:

• Sonia's unit rate was listed as 20 min. 1 problem and 25 min. 1 problem in different statements. Given that 20 min is less than 25 min, it appears that the more credible rate for Sonia (since she has a completed task) is 20 min. 1 problem.

• Maryna's unit rate of 1 min. 25 problems translates to 0.04 min. 1 problem, which is less time per problem compared to both unit rates for Sonia.

Conclusion: Sonia spent more time writing per problem than Maryna, with Sonia's unit rate being 20 min. 1 problem.

So the final answer is:
Sonia spent more time writing per problem at the unit rate of 20 min. 1 problem.
