Given:
Time spend on every 2 questions = 5 minutes.
To find:
The missing values for the given table.
Solution:
Let x be the number of questions and y be the number of minutes.
We have,
Time spend on every 2 questions = 5 minutes
Time spend on 1 question = [tex]\dfrac{5}{2}=2.5[/tex] minutes
Time spend on x questions = [tex]2.5x[/tex] minutes
Now,
[tex]y=2.5x[/tex]
For x=0,
[tex]y=2.5(0)=0[/tex]
For x=1,
[tex]y=2.5(1)=2.5[/tex]
For x=2,
[tex]y=2.5(2)=5[/tex]
For x=3,
[tex]y=2.5(3)=7.5[/tex]
For x=4,
[tex]y=2.5(4)=10[/tex]
Therefore, the required table is
Questions : 0 1 2 3 4
Time (minutes) : 0 2.5 5 7.5 10
