Answer 2

Answer:

20 minutes

Step-by-step explanation:

From the given information, we can see that:

• 4 minutes burns 20 calories, and
• 8 minutes burns 40 calories.

We can see the pattern that minutes x 5 = number of calories.

4*5 =20

8*5=40

So for the last line, what we need is a number which multiplied by 5 gives us 100. Let that number be $x$:

$x*5=100\\5x=100\\x=\frac{100}{5}=20$

So you would need to run 20 minutes.
