A track runner ran for 15 minutes, walked for 15 minutes, ran for another 20 minutes, and then stretched in place for 10 minutes
.Which graph describes the relationship between runner's total distance and time?
1 answer:
Note that:
When the track runner runs, he is expected to cover more distance than when walks
When he stretches his body, he is not expected to cover any distance because there is no motion when the body is stretched in place.
By carefully observing the graphs shown, the correct graph will be plotted in the format below:
Long distance for the first 15 minutes
Short distance for the second 15 minutes
Longer distance for the next 20 minutes
No distance covered in the last 10 minutes
Therefore, the only graph that describes the relationship between the runner's total distance and time is option B

For this case we must say that it is obtained by multiplying any even number of negative numbers, that is, if a positive or negative number is obtained.
We must bear in mind that the Law of Signs states that:
For example:
Let -a, -b, -c, -d negative numbers, we have:
- A pair:
- Two pairs:
This is true for the multiplication of any pair of negative numbers.
So, the answer is: You get a positive number
Answer:
A positive number is obtained
