Based on the tables showing the number of minutes two writers spent writing math problems for two different lessons, who spent more time writing per problem? Write the answer in unit rate form. (1 point) Responses Sonia spent more time writing per problem at the unit rate of 20 min. 1 problem . Sonia spent more time writing per problem at the unit rate of 20 min. 1 problem . Maryna spent less time writing per problem at the unit rate of 1 min.25 problems . Maryna spent less time writing per problem at the unit rate of 1 min.25 problems . Sonia spent the same amount of time as Maryna time writing per problem at the unit rate of 25 min.1 problem . Sonia spent the same amount of time as Maryna time writing per problem at the unit rate of 25 min.1 problem . Maryna spent more time writing per problem at the the unite rate of
1 min. 25 problems.
1 min. 0.8 problems.
To determine who spent more time writing per problem, we need to calculate the unit rate for each writer.
To find the unit rate, we divide the total time spent writing by the number of problems written.
Let's take a look at the information provided.
Sonia's data:
- Total time spent writing: 20 minutes
- Number of problems written: 1 problem
To calculate Sonia's unit rate, we divide the total time spent writing by the number of problems written:
Unit rate for Sonia = Total time spent writing / Number of problems written
= 20 minutes / 1 problem
= 20 min/1 problem
= 20 min
Therefore, Sonia's unit rate is 20 minutes per problem.
Maryna's data:
- Total time spent writing: 1 minute
- Number of problems written: 25 problems
To calculate Maryna's unit rate, we divide the total time spent writing by the number of problems written:
Unit rate for Maryna = Total time spent writing / Number of problems written
= 1 minute / 25 problems
= 1 min/25 problems
= 1 min
Therefore, Maryna's unit rate is 1 minute per 25 problems.
Comparing the unit rates, we can see that Sonia spent more time writing per problem. The unit rate for Sonia is 20 minutes per problem, while the unit rate for Maryna is 1 minute per 25 problems.
