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 =
`(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
