It takes Maya 30 minutes to solve 5 logic puzzles. At this rate, how many logic puzzles does she solve in 1 hour 30 minutes?

15

Step-by-step explanation:

If it takes her 30 minutes to solve 5 puzzles, then at that rate, she would solve 15 logic puzzles in 1 hour and 30 minutes.

5 = 30

30 must equal 90 (1 hour and 30 minutes)

3 (30)

However, you must do to the other side by what you do of one.

5 (3) = 30 (3)

15 = 90

30 minutes = 5 puzzles

60 minutes = 10 puzzles

90 minutes = 15 puzzles

She will solve 15 puzzles in an hour and 30 minutes
