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.
25 min.
Answer: Maryna spent more time writing per problem at the unit rate of
25 minutes/1 problem
Describe as a 7th grade enough to fit in a small text box.

Answer 1

To find out who spent more time writing per problem, we can calculate the unit rate for each writer by dividing the total minutes by the number of problems they solved.

For Sonia:

• For 6 problems: 120 minutes ÷ 6 = 20 minutes/problem
• For 18 problems: 360 minutes ÷ 18 = 20 minutes/problem
• For 25 problems: 500 minutes ÷ 25 = 20 minutes/problem
• For 60 problems: 1200 minutes ÷ 60 = 20 minutes/problem

Sonia's unit rate is 20 minutes/problem.

For Maryna:

• For 8 problems: 200 minutes ÷ 8 = 25 minutes/problem
• For 15 problems: 375 minutes ÷ 15 = 25 minutes/problem
• For 20 problems: 1250 minutes ÷ 20 = 62.5 minutes/problem

Maryna's unit rate is 25 minutes/problem.

Conclusion: Maryna spent more time writing per problem at a unit rate of 25 minutes/problem.

Answer 2

can you shorten it more

Answer 3

To find out who spent more time writing per problem, we calculate the unit rate for each writer.

Sonia:

• 6 problems: 120 minutes ÷ 6 = 20 minutes/problem
• 18 problems: 360 minutes ÷ 18 = 20 minutes/problem
• 25 problems: 500 minutes ÷ 25 = 20 minutes/problem
• 60 problems: 1200 minutes ÷ 60 = 20 minutes/problem

Sonia's unit rate: 20 minutes/problem.

Maryna:

• 8 problems: 200 minutes ÷ 8 = 25 minutes/problem
• 15 problems: 375 minutes ÷ 15 = 25 minutes/problem
• 20 problems: 1250 minutes ÷ 20 = 62.5 minutes/problem

Maryna's unit rate: 25 minutes/problem.

Conclusion: Maryna spent more time writing per problem at 25 minutes/problem.
