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 =
(5)/(2)=2.5 minutes

Time spend on x questions =
2.5x minutes

Now,


y=2.5x

For x=0,


y=2.5(0)=0

For x=1,


y=2.5(1)=2.5

For x=2,


y=2.5(2)=5

For x=3,


y=2.5(3)=7.5

For x=4,


y=2.5(4)=10

Therefore, the required table is

Questions : 0 1 2 3 4

Time (minutes) : 0 2.5 5 7.5 10
