Algebra II Word Problem

Question

You have 46 minutes to take an exam of 28 questions. After you finish the first 12 questions you realize you must answer the remaining questions twice as fast to finish the exam. How many questions per minute were you answering?

Answer 1

46/28 = 1.643 min/question

 

(1.643)*12 = 19.71 min.

 

46 - 19.71 = 26.29 min.

 

so after 12 questions answered there are 16 questions left:

 

16/ 26.29 = .609 questions/min.
