Question

You’re taking an exam in math, and you spend 5 minutes for every 2 questions you answer on the test.(Plz answer! I’m failing and I need to get this correct!)

Answer 1

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 = $\dfrac{5}{2}=2.5$ 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
