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.
To determine who spent more time writing per problem, we need to calculate the unit rate for each writer.
For Sonia:
Number of problems = 6
Minutes of writing = 120
Unit rate = Minutes of writing / Number of problems = 120 / 6 = 20 minutes/problem
For Marnya:
Number of problems = 8
Minutes of writing = 200
Unit rate = Minutes of writing / Number of problems = 200 / 8 = 25 minutes/problem
Comparing the unit rates, we can see that Sonia spent more time writing per problem, with a unit rate of 20 minutes/problem.
