Given the statement:
Irina has 3 hours to finish her final math exam.
Determine her average time on each question if there are 45 questions on the exam.
Solution:
In order to determine her average time on each question, we simply needed to divide 180 minutes by 45. We use 180 since 1 hour is 60 minutes, and 3 hours is equal to 180 minutes.
= 180 minutes /45
= 4 minutes
Final answer:
Irina spent an average of 4 minutes per question.
