Answer: 2 .5 questions
Step-by-step explanation:
Given : Jill can answer 50 math questions every 20 minutes
To find the number of questions Jill can answer in one minute , we need to divide 50 by 20 , we get
The number of questions she complete in one minute = [tex]\dfrac{50}{20}[/tex]
i.e. The number of questions she complete in one minute = [tex]2.5[/tex]
So she complete 2 and a half questions per minute.
