QuestionShawna does her math homework every night. Last night, Shawna spent 45 minutes solving 15 math problems. Tonight, she needs to solve 10 math problems.
If she does them at the same rate, how many minutes will Shawna spend solving tonight's math problems? \square minutes

Studdy Solution
Use the rate to calculate the time needed to solve 10 problems.
Time for 10 problems=10 problems×3 minutes per problem=30 minutes\text{Time for 10 problems} = 10 \text{ problems} \times 3 \text{ minutes per problem} = 30 \text{ minutes}
The number of minutes Shawna will spend solving tonight's math problems is:
30 minutes\boxed{30 \text{ minutes}}
