Question

What was the hiker's total displacement?



A.
4 km north

B.
14 km northeast

C.
24 km

D.
0 km

Answer 1

Add all the numbers up. That's how you'd get your answer.

Answer 2

So you'd add 6+4+6+8 which equals what?

Answer 3

24

Answer 4

yes!

Answer 5

oh so i was right it is C

Answer 6

Yes you were Clara

Answer 7

but the next question was the distance the hiker walked so do the questions have the same answer?

Answer 8

Does it have the same exact numbers?

Answer 9

yup

Answer 10

Then yes, because the hiker had walked all that way.

Answer 11

alright thank you

Answer 12

alright i actually have another question with the same table so it say the average velocity during part a of the hike ....what does that mean?

Answer 13

Do you know what velocity means?

Answer 14

the rate of change

Answer 15

No, the speed of something in a given direction.

Answer 16

oh okay

Answer 17

Do you know how to find that?

Answer 18

i actually dont know how to find that

Answer 19

What number is the most common?

Answer 20

It's asking how to find the average speed/distance per each hour hiking. Where the hiker traveled 6 then 4 then 6 then 8. the hikers average speed is 6km and hour

Answer 21

looks like 3 in the entire chart if thats what your asking

Answer 22

But, the times aren't the exact same. Give me a moment

Answer 23

I'd say 6km

Answer 24

will you show me how you got that please?

Answer 25

6 is the common time per hour. the hiker traveled on 4 after 45 min and after an hour and a half the hiker got to 8. the common time is 6km per hour. I don't really know how to explain it well >.<

Answer 26

thank you so much!

Answer 27

Actually, you will have to sketch this out. Displacement is the distance between the starting point and the ending point only. It is not the same as distance. It is actually 4km north. Displacement is a vector quantity where distance is scalar. Scalar only has magnitude as you would use in saying "24 km" where vectors have magnitude AND direction in saying "4 km north"

Answer 28

And for velocity, you use displacement instead of distance in the calculation. Hence, you will have a direction to it as well.

You should have asked this in math/physics. :)
