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
i pont)
Sona spent more time writing per protem at the und rate of
Sona spent the same amount of time Maryna meeting perpetrate of
Maryna
To get the answer, we need to calculate the unit rate for each writer, which is the number of minutes spent writing divided by the number of problems.
For Sonia:
Number of problems = 10 + 25 + 60 = 95
Minutes of writing = 120 + 360 + 500 = 980
Unit rate = Minutes of writing / Number of problems = 980 / 95 ≈ 10.32
For Maryna:
Number of problems = 200 + 20 + 50 = 270
Minutes of writing = 15 + 375 + 500 = 890
Unit rate = Minutes of writing / Number of problems = 890 / 270 ≈ 3.30
Comparing the unit rates, we can see that Sonia spent more time writing per problem with a unit rate of approximately 10.32, while Maryna had a unit rate of approximately 3.30.
To determine who spent more time writing per problem, we need to calculate the unit rate for each writer. The unit rate is found by dividing the total minutes of writing by the number of problems.
For Sonia:
Total minutes of writing = 120 + 360 + 500 + 60 + 1,200 = 2,240
Number of problems = 10 + 25 = 35
Unit rate for Sonia = 2,240 / 35 = 64 minutes/problem
For Magula:
Total minutes of writing = 15 + 20 + 50 + 1,250 = 1,335
Number of problems = 200
Unit rate for Magula = 1,335 / 200 = 6.675 minutes/problem
Comparing the unit rates, we can conclude that Sonia spent more time writing per problem, with a unit rate of 64 minutes/problem.
